The correct answer is B because gcloud components list provides a comprehensive list of all available components in the Cloud SDK, including their installation status. This command is essential for identifying the correct component name for installation.

• Option A & C are incorrect as they pertain to viewing and editing Cloud SDK properties, not listing components.
• Option D is incorrect because it is not a valid command.

For more details, refer to the GCP documentation on Cloud SDK Components List. This command not only lists the components but also provides information on their status, name, ID, and size. Additionally, using the –show-versions flag will display the installed and latest available versions of each component.
