Why each option

Worker nodes are the machines in a Kubernetes cluster where containerized applications (pods) actually run.

AWorker NodeCorrect

Worker nodes host the pods, which are the smallest deployable units containing containers, and manage their lifecycle through the kubelet agent. They provide the compute, memory, and storage resources for the application workloads.

Bkube-proxy

Kube-proxy maintains network rules on nodes, enabling network communication to your Pods from inside or outside the cluster, not running workloads.

CControl plane

The control plane manages and orchestrates the worker nodes and pods, but does not directly run the application container workloads itself.

Detcd

etcd is a distributed key-value store used by Kubernetes to store all cluster data, not for running container workloads.
