Explanation

A DaemonSet ensures that a copy of a specified Pod runs on all (or a selected subset of) nodes in the cluster. As nodes are added to the cluster, pods are automatically added to them; as nodes are removed, those pods are garbage collected. Common use cases include node monitoring agents, log collectors (e.g., Fluentd), and network plugins. Option B (kubelet management) is handled by the system, not DaemonSets. Option C describes a ReplicaSet/Deployment. Option D is close but imprecise - a DaemonSet runs a Pod (which may contain one or more containers/processes), not just a bare process.
