Multiple choiceMediumchapter-15-curatedpremiumconcurrencysemaphores-timeouts-and-cancellation
Answer and explanation
Correct answer
C. Make the rule clearer and easier to explain. Apply limits and timeouts so one slow dependency or surge does not saturate the rest of the workflow.
Why
The best review comment anchors the change to readability, correctness, and future maintenance. Unlimited concurrency often looks impressive in a demo and dangerous in production.
