The provided item consists of a complex multi-part finance question with several decision points (arbitrage existence, portfolio construction, and a no-dividend scenario), but the given data for the multiple-choice selections is incomplete: there are no explicit answer options listed for the selections, and the "answer" field is null with an empty set of answer_options. Because of this, I cannot definitively label any option as correct or incorrect. Instead, I will walk through the relevant reasoning and the standards you would apply to each part if the answer choices were present, so you can map the logic to the actual options once they are available.

Part (i): Are there any arbitrage opportunities?
- Start by understanding the forward price relationship with today’s stock price, the risk-free rate, and any known dividends. In a standard no-arbitrage framework, the forward price F0,T is related to the spot price S0, the risk-free rate r (continuously compounded), and the present value of known dividends PV(D) by F0,T = (S0 - PV(D)) e^{rT}, where PV(D) is the sum of the present values of known cash dividends paid before or at the delivery date.
- The given data provide: S0 = 185, the continuously compounded risk-free rate r = 5% (0.05), the forward price is described as the discounted value today of the forward price for delivery in 6 months equals 185, and the present value of a dividend paid at 3 months is 10. Discrepancies or inconsistencies in these numbers relative to the standard formula would signal an arbitrage opportunity. For instance, if the implied forward price derived from the data differs from the observed forward, one could construct a zero-cost, risk-free portfolio that yields a positive payoff today and zero thereafter.
- The actual right answer (yes or no) hinges on whether the given numbers satisfy the no-arbitrage equality F0,T = (S0 - PV(D)) e^{rT} under the 6-month horizon with a known dividend PV = 10 at 3 months. If the supplied forward value is consistent with this relation, there is no arbitrage; if not, there is arbitrage.
- Important pitfall: ensure you’re using the correct discounting for the dividend (PV(D) is already discounted to today) and the correct compounding convention for the forward (continuous compounding here). If the numbers don’t line up, the arbitrage signal could be to long/short the forward and take offsetting positions in the stock and/or debt to lock in a risk-free profit.

Part (ii): If there is an arbitrage opportunity, construct a portfolio with strictly positive cash flow today and zero cash flow at 3 and 6 months.
- The goal is to assemble a self-financing strategy that requires an initial positive cash inflow (today) and guarantees no cash flow at the future dates (3 and 6 months). The exact construction depends on the sign and magnitude of the mispricing in the forward relative to the stock and the dividend.
- A typical arbitrage construction would involve taking positions in three components: (a) a position in the forward (long or short depending on mispricing), (b) a stock position (long or short), and (c) a position in a risk-free account to fund or invest the required cash today and to capture or neutralize cash flows at 3 and 6 months, including the PV of the dividend at 3 months.
- The selection tips (Forward position, PV(Forward) position in risk-free asset, Stock position, PV(Dividend) position in risk-free asset) would require determining the correct signs (long/short) and whether to borrow or lend to achieve zero cash flows at 3 and 6 months while collecting a positive cash flow today. If an arbitrage exists, there is at least one combination that satisfies these constraints.

Part (iii): Now assume Apple is expected to pay no dividends in the next 6 months. Is there still an arbitrage opportunity?
- Removing the dividend simplifies the forward-price relationship to F0,T = S0 e^{rT} for a dividend-free asset. If the given forward price is inconsistent with this dividend-free relation (i.e., F0,T != S0 e^{rT}), an arbitrage would persist even without dividends. Conversely, if the forward price matches the dividend-free no-arbitrage condition, there is no arbitrage.
- The key test is whether the forward price implied by the data equals S0 e^{rT} with T = 0.5 years. If there is any deviation, you can construct a risk-free portfolio by trading the forward and the stock (and possibly borrowing or lending at the risk-free rate) to lock in a zero-net investment today and a nonnegative payoff later, effectively an arbitrage.

What you should do once you have the actual answer options:
- For each option in (i), evaluate whether it aligns with the no-arbitrage condition F0,T = (S0 - PV(D)) e^{rT}. If the forward price today’s discounted value matches this formula, the option stating no arbitrage is correct; if not, the arbitrage option is correct.
- For (ii), pick the combination of forward, stock, and cash positions that yields a positive cash flow today and zero cash flows at 3 and 6 months. You’ll need to set the signs (long or short) based on whether you’re exploiting an overpriced or underpriced forward relative to the theoretical price, and you’ll decide borrow/lend based on the necessary funding to achieve self-financing zero-cash future dates.
- For (iii), repeat the arbitrage check with the dividend assumed to be zero. If the no-dividend forward relationship is violated, there is arbitrage; if it exactly agrees, there isn’t.

Important caveat about the current prompt data
- Because the present question payload lacks explicit answer options (the selections for the dropdowns are not provided) and the answer field is null, I cannot label any particular choice as correct or incorrect here. To proceed to a concrete, instructional answer, please supply the specific option texts for (i), the four dropdowns in (ii) (Forward position, PV Forward funding, Stock position, PV Dividend funding), and the two options for (iii). With those, I can map each option to a precise justification, including why the others are wrong, and provide a step-by-step, diverse explanation that line-breaks for readability.
