Answer: Relocate the Lambda function to the same VPC as the RDS, ensuring mutual security group allowances.
The correct answer is B. The issue is that the Lambda function cannot connect to the RDS database because they reside in different VPCs. Redeploying the Lambda function in the same VPC as the RDS instance will allow it to establish a direct connection, ensuring that proper routing and security group configurations are in place to permit traffic between the Lambda function and the RDS database.
