The correct answer is:
C. nodeSelector: disktype: ssd
nodeSelector tells Kubernetes to schedule the Pod only on nodes that have matching labels.
Example:
spec:
nodeSelector:
disktype: ssd
The node must have this label:
kubectl label node node-1 disktype=ssd
Why not the others?
annotations add metadata, not scheduling rules.
labels identify objects, but do not schedule Pods by themselves.
resources define CPU/memory requests and limits.
Answer: C.
