Refer to the exhibit. A developer needs to scale the existing pods within the worked nodes. Which object should be edited to achieve this goal?

A ReplicaSet's primary function in Kubernetes is to ensure a specified number of identical pods are running at all times. Directly editing the `replicas` field within an existing ReplicaSet's manifest allows for immediate scaling up or down of the managed pods. While Deployments often manage ReplicaSets, the ReplicaSet is the direct controller of pod count.

PriorityClass is used to indicate the priority of a pod and influence its scheduling, not to control the number of pod replicas.

While a Deployment *creates and manages* ReplicaSets for scaling, editing the Deployment is the higher-level abstraction. However, the ReplicaSet is the Kubernetes object that directly ensures and controls the specified number of running pod replicas.

Pods are individual instances of a running process; they are not scalable themselves and are managed by higher-level controllers like ReplicaSets or Deployments.
