Selected Answer: A
Deployments and ReplicaSets are closely related in Kubernetes. A Deployment is a higher-level abstraction that manages ReplicaSets and provides declarative updates to Pods. When you create or update a Deployment, Kubernetes automatically creates or updates the underlying ReplicaSet to match the desired state specified in the Deployment.

Selected Answer: A
Deployments are higher-level abstractions in Kubernetes that manage ReplicaSets.ReplicaSets, on the other hand, are lower-level controllers responsible for maintaining a specified number of identical Pods to ensure high availability and fault tolerance. ReplicaSets are used by Deployments to manage the lifecycle of Pods, including scaling, rolling updates, and maintaining a desired number of replicas.
