Selected Answer: D
he Kubernetes component responsible for watching newly created Pods with no assigned node and selecting a node for them to run on is the kube-scheduler. The kube-scheduler is a control plane component that continuously monitors the Kubernetes API server for new Pods that are in a pending state (meaning they have not yet been assigned to a node). When it identifies such a Pod, it then performs a scheduling process to determine the most suitable node for that Pod to run on, considering various factors such as resource requirements, node availability, affinity/anti-affinity rules, and other policy constraints. Finally, it updates the Pod's definition in the API server to bind it to the selected node.
