kind: RoleBinding
metadata:
  name: read-pods
  namespace: dev
roleRef:
  kind: Role

Adefault namespace

BCluster-wide

Ckube-system namespace

Ddev namespace

Step-by-Step Solution

Solution:

Step 1: Check metadata namespace in RoleBinding
The RoleBinding has namespace: dev in its metadata, so it applies in the 'dev' namespace.
Step 2: Understand RoleBinding scope
RoleBindings are namespace-scoped, so they only apply in the namespace where they are created.
Final Answer:
The RoleBinding applies to the dev namespace. -> Option D
Quick Check:
RoleBinding namespace = binding scope [OK]

Quick Trick: RoleBinding namespace field sets scope [OK]
