Correct answer & explanation
✓
Run aws ec2 start-instances --instance-ids i-1a2b3c4d5e6f7g8h
The instance with ID i-1a2b3c4d5e6f7g8h is in a stopped state. To transition it to the 'running' state, the administrator should use the start-instances command. Option A is correct because it starts the stopped instance. Option B (stop-instances) would stop running instances, which is not the desired action. Option C (reboot-instances) would reboot a running instance, but this instance is stopped. Option D (terminate-instances) would permanently delete the instance, which is not the goal.
