The correct answer is a Pod.

A Pod is the smallest deployable unit in Kubernetes and it can host one or more containers. The Kubernetes scheduler assigns Pods to nodes and the node kubelet is responsible for starting the containers that belong to the Pod. Controllers and higher level objects create and manage Pods but the actual scheduling is performed at the Pod level.

Cloud Run is a managed serverless service on Google Cloud that runs containers outside of the Kubernetes scheduling primitives and it is not the object the kube-scheduler places on a node.

a Helm chart is a packaging and templating mechanism used to install Kubernetes resources. It generates manifests that may include Pods and controllers but it is not itself scheduled by Kubernetes.

a Deployment is a controller that declares desired state and manages ReplicaSets and Pods. It ensures the correct number of Pods exist but the scheduler does not schedule a Deployment directly.
