Explanation:
The correct answer is A. The developer should generate a data key using AWS Key Management Service (AWS KMS) and encrypt the files using the AWS Encryption SDK. AWS KMS allows for the creation of symmetric data keys, and the AWS Encryption SDK is designed to simplify encryption and decryption operations, making it the most suitable choice for implementing encryption within the application before uploading files to Amazon S3.
