Refer to the exhibit. Which code snippet completes this code to handle API rate-limit?

HTTP 408 represents a 'Request Timeout' error where the server did not receive a complete request in time; it is unrelated to rate limiting and checking for it would not correctly handle API throttling.

HTTP 408 represents a 'Request Timeout' and is not the correct status code for rate-limit detection; this choice is identical to choice A and equally incorrect.

HTTP status code 429 is defined in RFC 6585 as the standard indicator that the client has sent too many requests in a given time window and the server is rate-limiting the response. Using 'response.status_code != 429' as a loop or condition check allows the code to continue execution when the request is successful and to break or handle the retry logic specifically when rate limiting is encountered. Status 408 is a request timeout, which is a different error unrelated to rate limiting.

While 429 is the correct rate-limit status code, using '== 429' instead of '!= 429' inverts the intended logic for the conditional structure shown, causing the code to behave incorrectly for the retry-exit pattern depicted.
