A certain network consists of two ideal voltage sources and a large number of ideal resistors. The power consumed in one of the resistors is 4 W when either of the two sources is active and the other is replaced by a short circuit. The power consumed by the same resistor, when both the sources are simultaneously active, would be:

• A. Zero or 16 W
• B. 4 W or 8 W
• C. Zero or 8 W
• D. 8 W or 16 W
