The correct answer is C, AWS CodeCommit. AWS CodeCommit is a fully managed source control service provided by AWS that hosts private Git repositories. It is designed to be secure, scalable, and integrates well with other AWS services and development tools. This service is particularly useful for developers who are looking for a way to manage their code, repositories, and version controls in a secure and centralized manner within the AWS ecosystem. The other options, while related to development and deployment on AWS, do not specifically focus on hosting GitHub-based code and repositories as CodeCommit does.
