Step-by-Step Solution
Solution:
Step 1: Understand pod creation depends on selector matching template labels
If selector labels don't match pod template labels, ReplicaSet won't manage any pods.Step 2: Evaluate other options
Replicas 0 means no pods, but question says pods expected. Misspelled image causes pod crash, not zero pods. Name missing causes YAML error, not silent no pods.Final Answer:
The selector labels do not match the pod template labels -> Option BQuick Check:
Selector-template label mismatch = no pods [OK]
Quick Trick: Selector and template labels must match exactly [OK]

- Assuming image typo prevents pod creation
- Ignoring selector-template label mismatch
- Thinking ReplicaSet name is optional
