Your company operates in a highly regulated domain. Your security team requires that only trusted container images can be deployed to Google Kubernetes Engine (GKE). You need to implement a solution that meets the requirements of the security team while minimizing management overhead. What should you do?

A. Configure Binary Authorization in your GKE clusters to enforce deploy-time security policies. B. Grant the roles/artifactregistry.writer role to the Cloud Build service account. Confirm that no employee has Artifact Registry write permission. C. Use Cloud Run to write and deploy a custom validator. Enable an Eventarc trigger to perform validations when new images are uploaded. D. Configure Kritis to run in your GKE clusters to enforce deploy-time security policies.
