RZ (Return-to-Zero) is the only binary signaling technique that reduces the voltage to zero during the transmission of a 1 bit before the bit period ends. NRZ (Non-Return-to-Zero) techniques maintain a high or low voltage throughout the duration of the bit, while NRZ-I (Non-Return-to-Zero Inverted) changes the voltage only if the bit is different from the previous one. Therefore, C is the best choice.
