Answer: Cloud Build

The correct answer is **Cloud Build**. While **Cloud Source Repositories** provides a private Git repository for source code management, it lacks dedicated CI/CD capabilities. **Cloud Functions** is a serverless compute platform for event-driven functions, not a CI/CD platform. **Cloud Deployment Manager** aids in infrastructure provisioning through declarative configurations but doesn't offer native CI/CD features. **Cloud Build**, however, is specifically designed as a fully managed CI/CD platform in GCP, enabling the definition of build pipelines, automated builds triggered by source code changes, and seamless integration with other GCP services for comprehensive continuous integration and delivery solutions.
