Selected Answer: C

Answer: C. Enable throttling on APIs When APIs are overwhelmed by a few heavy users during peak hours, throttling (or rate limiting) is typically the most cost-effective way to ensure that all customers have fair access. By limiting each user to a defined request rate, you prevent any single user (or small group) from exhausting resources and degrading performance for everyone else.
