You ran kubectl create -f service.yaml but got an error saying the service already exists. What should you do to update the service instead?

AUse <code>kubectl replace -f service.yaml</code> to update the service.

DRun <code>kubectl create -f service.yaml</code> with a different name.

kubectl create fails if the resource exists, so the error means the service is already present.

Final Answer:
Use kubectl apply -f service.yaml to update the existing service. -> Option C
