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.
