Final Answer :
A
Explanation :
The RTO (Retentive Timer On) timer requires a timer reset instruction to clear the accumulated time and restart the timer. This is in contrast to the TON (Timer On Delay) timer, which simply requires an input condition instruction to begin counting time. Therefore, the correct answer is A) timer reset instruction.
