A developer must review all the configuration that has been applied to set up a UI-based service called "UI". The code exists in the "master" namespace. Which command must be used to review and valida

`kubectl get services UI -n master` would only provide a summary of the service (like its name, cluster IP, external IP, ports), not the detailed configuration required for review and validation.

`kubectl describe service UI -all-namespaces` would attempt to describe a service named "UI" across all namespaces, which is inefficient and not specific to the "master" namespace where the service is known to exist.

The `kubectl describe` command provides a detailed view of a specific Kubernetes resource, including its configuration, status, and related events. By specifying `service UI` and the `-n master` flag, the command will output all relevant configuration and operational details for the "UI" service exclusively within the "master" namespace, which is exactly what the developer needs to review and validate its setup.

`kubectl describe UI -n master` is syntactically incorrect because `UI` alone is not a valid resource type; it needs to be prefixed with the resource type, such as `service` or `deployment`.
