C Correct answer
Explanation

When an automatically-starting service is stopped through SCM and then restarted, the service lifecycle methods invoked are OnStop (when stopping) followed by OnContinue (when resuming/restarting). This reflects that the service was running before and is continuing after the interruption. OnStart would be called for a fresh start from a stopped state, not a restart from a running state.
