- A. A component that controls access to the Kubernetes API
- B. A plugin that intercepts requests to the Kubernetes API server before object persistence
- C. A controller that manages the admission of new nodes to the cluster
- D. A user interface for approving new deployments

**Answer:** A plugin that intercepts requests to the Kubernetes API server before object persistence

They can validate, mutate, or reject requests based on custom logic, enforcing security policies, resource quotas, or other requirements.
