What does the --selector option do in a kubectl get command?

• A. Ignores labels and shows all resources
• B. Show only YAML data
• C. Filters and displays resources based on the provided label
• D. Filters by field selector only

Answer: (C)

Label selectors filter the resources you list by their labels. When you use the --selector option with kubectl get, Kubernetes only returns resources whose label expressions match what you provide. For example, kubectl get pods -l app=frontend will show only pods labeled with app=frontend, and you can combine multiple requirements like -l app=frontend,env=prod. The -l shorthand works the same as --selector. This filtering is about labels, not about YAML output or field-based filtering (which uses --field-selector).
