Answer and explanation
Correct answer
A. Make the rule clearer and easier to explain. Choose sync, asyncio, threads, or processes by the dominant bottleneck and the operational cost of complexity.
Why
The best review comment anchors the change to readability, correctness, and future maintenance. Starting from the tool name instead of the workload often leads to accidental architecture.
