   A Python script uses a function to fetch data from an API. The function sometimes raises a TimeoutError. The script currently crashes when this happens. The team wants the script to retry the API call up to three times with a 5-second delay between attempts, and then fail if all retries fail. What is the most appropriate implementation?

   • AWrap the API call in a for loop that attempts the call up to three times, catching TimeoutError and sleeping 5 seconds between attempts.
   • BUse a while loop that runs until the API call succeeds, with no attempt limit.
   • CCatch TimeoutError once and immediately retry the call a single time.
   • DIncrease the API client's timeout value to 60 seconds.
