Using the command `kubectl cluster-info` is the appropriate way to check the status of a Kubernetes cluster. This command provides essential information about the cluster, including the addresses of the master and the services running in the cluster, allowing you to quickly assess the overall health and accessibility of the cluster components.

The use of this command helps you verify that your cluster is running as expected. It also connects to the Kubernetes API server and retrieves vital data, making it a go-to command for monitoring cluster status.

Other choices do not represent valid commands in the context of Kubernetes:

- The command `kubectl get cluster` is not recognized, as `kubectl get` is generally used for retrieving resource details, and there isn't a `cluster` resource in that context.

- Similarly, `kubectl inspect cluster` does not exist; the `inspect` verb is not applicable to check cluster status.

- The command `kubectl status cluster` is also not valid as `kubectl status` is not a standard command, further confirming that `kubectl cluster-info` is the correct and recognized command to use for this purpose.
