Answer – D
The AWS Documentation mentions the following.
AWS CodeStar is a cloud-based service for creating, managing, and working with software development projects on AWS. You can quickly develop, build, and deploy applications on AWS with an AWS CodeStar project. An AWS CodeStar project creates and integrates AWS services for your project development toolchain. Depending on your choice of AWS CodeStar project template, that toolchain might include source control, build, deployment, virtual servers or serverless resources, and more. AWS CodeStar also manages the permissions required for project users (called team members). By adding users as team members to an AWS CodeStar project, project owners can quickly grant each team member role-appropriate access to a project and its resources.
Option A is incorrect since this service is used for managing CI/CD pipelines.
Option B is incorrect since this service is used for managing code builds.
Option C is incorrect since this service is used for managing source code versioning repositories.
