A stable network endpoint that load balances connections to a set of pods is correct because that succinctly describes the primary purpose of a Kubernetes Service within a cluster.

A Service provides a stable virtual IP and a DNS name that applications can use even when the underlying pods are created and destroyed. The Service selects matching pods and forwards traffic to their current IPs, and it also performs simple load balancing across those endpoints so clients do not have to track pod IPs themselves.

A collection of rules that governs ingress and egress connectivity between pods is incorrect because that describes a NetworkPolicy, which controls allowed traffic but does not provide a stable endpoint or load balancing.

An object for running batch or finite tasks that start, complete and then stop is incorrect because that describes a Job, which is used for one off or batch workloads and not for providing network endpoints.

A resource that ensures a workload runs with the desired number of replicas is incorrect because that describes a ReplicaSet or Deployment, which manage replica counts and rollout behavior but do not present a stable network endpoint or perform load balancing.
