A) retentive timer can be programmed for much longer time delay periods. B) nonretentive timer can be programmed for much longer time delay periods. C) retentive timer maintains the current time should power be removed from the device or when the timer rung goes false. D) nonretentive timer maintains the current time should power be removed from the device or when the timer rung goes false.
