Selected Answer: A
The correct answer is (A). Storing the API key as a Lambda environment variable using an AWS Key Management Service (AWS KMS) customer-managed key is the most secure solution. AWS KMS is a managed encryption service that provides customer-managed keys. Customer-managed keys are encrypted with an AWS KMS master key, which is stored in an AWS KMS vault.

Selected Answer: A
Lambda environment variables can be encrypted using a customer managed key in AWS KMS. This approach ensures that the API key is encrypted at rest and seamlessly integrated into the Lambda function. When the function is executed, it can access the decrypted value of the API key for authenticating with the third-party system.
