Final Answer :
D
Explanation :
A retentive timer retains its accumulated (AC) value even when the controlling input is off. Resetting a retentive timer is not dependent on the relationship between the accumulated time and preset time (AC and PR times), but rather on a specific reset command or function within the control program. Therefore, none of the conditions listed (A, B, C) are correct for resetting a retentive timer.
