Begin by noting what the question asks: to approximate the area under a curve on a given interval using a Riemann sum with n rectangles, and to identify which choice yields the most accurate approximation.

First, observe that there are no answer options provided in the data you gave. Without a set of candidate methods (e.g., left endpoints, right endpoints, midpoints, trapezoidal rule, etc.), we cannot evaluate and compare them directly for this specific curve.

In general terms:
- If the function is increasing on the interval, left-endpoint Riemann sums tend to underestimate the true area, while right-endpoint sums tend to overestimate.
- If the function is decreasing, left-endpoint sums tend to overestimate and right-endpoint sums tend to underestimate.
- Midpoint (or midpoint-based rules) often provide a more accurate approximation than both left and right sums for many smooth functions, because their error terms cancel more effectively and they have higher-order accuracy for well-behaved functions.
- The trapezoidal rule can also be more accurate than left/right sums for monotone functions, since it averages the left and right rectangle areas.

Without knowing the specific interval, the function’s behavior on that interval, and the given answer options, we cannot determine which method is truly the most accurate for this particular scenario.

If you can provide the missing answer options (e.g., left endpoints, right endpoints, midpoint, trapezoidal), and, if possible, the function or a description of its shape over the interval, I can give a precise analysis of which method yields the most accurate approximation and why.
