Suggested answer: C

Explanation:

In a Kubernetes environment, the Admission Controller is a critical component responsible for approving, modifying, or rejecting administrative requests before they are processed by the Kubernetes API server. The Admission Controller acts as a gatekeeper, enforcing governance and policy controls by evaluating requests against a set of predefined rules and policies. It can validate and mutate requests, ensuring that only compliant and authorized changes are allowed to proceed. This capability is vital for maintaining the security and integrity of the Kubernetes cluster, as it can prevent unauthorized or potentially harmful actions from being executed, thus playing a key role in the cluster's overall security posture.
