Why each option
The kubelet is the primary agent that runs on each worker node, ensuring containers are running in pods according to the specifications provided by the API server.
The kubelet is an agent that runs on each node in a Kubernetes cluster, responsible for receiving PodSpecs from the API server and ensuring that the containers described in those PodSpecs are running, healthy, and configured correctly on its node.
systemd is an init system and service manager for Linux operating systems, not a Kubernetes-specific agent.
kube-proxy is a network proxy that runs on each node and maintains network rules to enable network communication to Pods, distinct from the kubelet's role in managing Pods.
A pod is the smallest deployable unit in Kubernetes, encapsulating containers and resources, not an agent that runs on the node itself.
