ReadWriteOnce (RWO): Volume can be mounted as read-write by a single node.

ReadOnlyMany (ROX): Volume can be mounted as read-only by many nodes.

ReadWriteMany (RWX): Volume can be mounted as read-write by many nodes.

ReadWriteOncePod (RWOP): Volume can be mounted as read-write by a single pod (more restrictive than RWO).

The optimal answer is b) ReadOnlyMany, ReadWriteOncePod because:

1. ROX allows all pods that need to read the data to do so simultaneously across multiple nodes

2. RWOP ensures that only one pod (not just one node) has write access at any time

3. This combination adheres to the principle of least privilege by not granting unnecessary write permissions to pods that only need to read
