Correct answer & explanation
✓
kubesec
Kubesec is a static analysis tool that evaluates Kubernetes manifests (YAML files) against security best practices and provides a security score. Cosign (A) is for container signing and verification, Syft (B) is for generating SBOMs, and Clair (D) is for container vulnerability scanning. Therefore, option C is correct.
