Which of these commands is used to retrieve the documentation and field definitions for a Kubernetes resource?

The kubectl explain command is used to get detailed documentation about a specific Kubernetes resource and its fields. By running kubectl explain , a user can see a description of the resource, its purpose, and a list of all the fields it supports. It can be used recursively to explore nested fields (e.g., kubectl explain pods.spec.containers). This command fetches the documentation directly from the API server, ensuring it matches the cluster's version.

B. kubectl api-resources: This command lists the available API resource types on the server, but does not provide documentation for their fields.
C. kubectl get --help: This command displays the help text and available flags for the kubectl get command itself, not for a specific resource type.
D. kubectl show: This is not a standard kubectl command. The command to display details of a specific resource is kubectl describe.
