Answer: Binary Authorization

The correct answer is **Binary Authorization**. This GCP feature ensures the quality and integrity of your software by automatically checking each component of your software supply chain before deployment. It uses policy-based controls to enforce security and compliance checks on container images and their metadata, allowing only trusted and approved images to be deployed to production. - **Container Analysis** provides visibility into container images' contents and provenance, scanning for vulnerabilities and compliance with policies, but it doesn't automatically check each component of the supply chain. - **Google Kubernetes Engine (GKE)** facilitates running Kubernetes clusters on GCP for managing containerized applications but doesn't perform automatic checks on software supply chain components. - **Container Registry** offers a secure and scalable solution for storing and managing container images but lacks the automatic verification feature of Binary Authorization.
