2. The system's application interfaces enable the creation of add-ons across various layers.
3. The sharing of stack data facilitates the creation of interoperable applications through the stack.
4. In contrast to Bitcoin, existing payment networks operate as closed systems with no interoperability.

A. All are True.
B. 1, 2, 3 are True.
C. 2, 3, & 4 are True.
D. 1, 2, & 4 are True.

The question asks us to evaluate which combination of statements about the Bitcoin payment system the writer asserts as true, given four numbered statements and four multiple-choice options.

Option A: All are True.
- If we take statement 1 to say there is provision for user interaction at every level, this aligns with Bitcoin’s design that enables user participation across layers of the system.
- Statement 2 claims the system's application interfaces enable the creation of add-ons across various layers, which would reflect extensibility via APIs, plugins, or developer tools at multiple layers.
- Statement 3 states that sharing stack data facilitates interoperable applications through the stack, suggesting transparency or data sharing across components to allow cross-layer interoperability.
- Statement 4 asserts that existing payment networks are closed systems with no interoperability, serving as a contrast to Bitcoin’s openness.
If the writer indeed endorses all four claims, this option would be internally consistent with a view that Bitcoin is modular, extensible, interoperable, and contrasted with closed networks.

Option B: 1, 2, 3 are True.
- This implies statement 4 is false, i.e., the writer believes that existing payment networks are not necessarily closed with no interoperability.
- The evaluation would hinge on whether the writer sees interoperability as extending to traditional networks, which would contradict statement 4.
- The rationale would accept user interaction, add-on interfaces, and stack data sharing as true, but reject the claim about traditional networks being entirely closed.

Option C: 2, 3, & 4 are True.
- This set excludes statement 1, meaning the writer does not consider there to be provision for user interaction at every level.
- It includes the assertion that add-ons across layers (2) and stack data sharing enabling interoperability (3) are true, and also that traditional networks are closed with no interoperability (4).
- The absence of statement 1 would require the writer to discount the pervasiveness of user interaction across levels, which may conflict with a broadly interactive design perspective.

Option D: 1, 2, & 4 are True.
- This combination claims user interaction at every level (1), add-on interfaces across layers (2), and that traditional networks are closed with no interoperability (4).
- It excludes statement 3 about sharing stack data enabling interoperable applications (3). If the writer emphasizes interoperability through stack data sharing, this option would omit a key interoperability mechanism.
- The removal of statement 3 would create tension if the writer views stack data sharing as a cornerstone of cross-layer interoperability.

In evaluating these options, you would weigh how the writer characterizes Bitcoin’s openness, extensibility, and interoperability in contrast to traditional payment networks. Consider whether the writer depicts interoperability as a property arising from data sharing across the stack and from extensible interfaces, and whether this implies that traditional networks are entirely closed or merely less interoperable.
