Selected Answer: B
A NetworkPolicy in Kubernetes is a resource that defines rules for controlling the network traffic to and from Pods. NetworkPolicies allow you to specify how groups of Pods are allowed to communicate with each other and with other network endpoints. By default, Pods are non-isolated, meaning they accept traffic from any source. When a NetworkPolicy is applied, it can classify Pods as isolated, meaning they only accept traffic that matches the specified rules.
