A developer has created an AWS Lambda function that interacts with an Amazon Aurora MySQL database.
The Lambda function makes queries to the database. After a performance test for the Lambda function, the database starts to show an error for too many connections.
Which solution will solve this problem with the LEAST operational effort?

A. Create a road replica for the database. Query the replica database instead of the primary database.
B. Migrate the data to an Amazon DynamoDB database.
C. Sot a limit to the Lambda function's concurrency.
D. Create a proxy in Amazon RDS Proxy. Query the proxy instead of the database.
