The component of the node responsible for running workloads is the kubelet. While the container runtime (like Docker, containerd, or CRI-O) is crucial for actually running the containers, the kubelet is the orchestrator that ensures the containers are running as specified by the Kubernetes control plane.

Selected Answer: A
B. The kubeproxy Incorrect. kube-proxy is responsible for maintaining network rules on nodes and ensuring that network traffic is correctly routed to the appropriate Pods. It is not responsible for running workloads. C. The kube-apiserver Incorrect. The kube-apiserver is a central component of the Kubernetes control plane that exposes the Kubernetes API. It handles API requests and updates the state of the cluster but does not run workloads. D. The container runtime Incorrect. While the container runtime (e.g., Docker, containerd) is responsible for running containers, it is the kubelet that manages the lifecycle of those containers and ensures they are running according to the Pod specifications.

Selected Answer: D
The container runtime is responsible for running the containers that make up the workloads on the node. The kubelet interacts with the container runtime to start, stop, and manage containers, but it is the container runtime itself that actually runs the workloads.
