Why each option
A Pod is the smallest deployable unit in Kubernetes, designed to package one or more containers along with their shared storage and network resources for scheduling.
A Pod is the basic execution unit in Kubernetes, encapsulating one or more tightly coupled containers that share the same network namespace, IP address, and storage volumes. Pods are the units that are scheduled onto nodes in a cluster.
`ContainerSet` is not a standard Kubernetes resource type.
A ReplicaSet is responsible for maintaining a stable set of running Pods at any given time, but it manages Pods rather than being the direct packaging unit for containers.
A Deployment manages ReplicaSets and provides declarative updates to Pods and ReplicaSets, but it does not directly package containers; Pods are the packaging unit.
Concept tested: Kubernetes Pod as a unit of deployment
