A Developer is investigating an issue whereby certain requests are passing through an Amazon API Gateway endpoint /MyAPI, but the requests do not reach the AWS Lambda function backing /MyAPI. The Developer found that a second Lambda function sometimes runs at maximum concurrency allowed for the given AWS account.
How can the Developer address this issue?

A. Manually reduce the concurrent execution limit at the account level
B. Add another API Gateway stage for /MyAPI, and shard the requests
C. Configure the second Lambda function’s concurrency execution limit
D. Reduce the throttling limits in the API Gateway /MyAPI endpoint
