Selected Answer: D
Container Runtime: The container runtime is the software that actually runs and manages containers on a node. Examples of container runtimes include Docker, containerd, and CRI-O. The container runtime is responsible for managing the lifecycle of containers, and it is a critical component for running containerized applications in a Kubernetes cluster.
