  B. Labels Explanation: In Kubernetes, labels are the primary mechanism used to identify and group objects such as Pods, Services, Deployments, etc. 🔖 Labels Key-value pairs attached to objects Used to organize, select, and operate on subsets of objects Breakdown of the other options: A. Custom Resources → ❌ Extend Kubernetes functionality, not used for grouping. C. Label Selector → ❌ Used to query or select objects based on labels, but not the grouping mechanism itself. D. Pod → ❌ A workload object, not a grouping mechanism.
