You are hosting a romantic candlelight dinner in your room, but you forgot to buy the candles and all the stores are closed. Your desk lamp is too white and too bright to provide the right ambience, so you modify it by inserting a diode between one of the power wires and the bulb. As the result of this change, the lamp emits a reddish glow that's roughly half a bright as without the diode. Just for fun, you reverse the diode so that the end that used to connect to the AC power wire is now connected to the bulb and vice versa. As the result of this reversal, the lamp
A. emits a deep reddish glow that is roughly half as bright as before you reversed the diode and a quarter as bright as without the diode at all.
B. no longer glows at all because no current flows through the diode.
C. still emits the same reddish glow that it emitted before you reversed the diode.
D. emits a brilliant bluish glow that's roughly twice as bright as without the diode.
