If a receiver is underselective:
A) more than one radio station on different frequencies may be picked up by the receiver at the same time
B) only part of the bandwidth of the AM signal is amplified, causing some of the sideband information to be lost and distortion results.
C) when the volume control is turned up to maximum, the desired station is very weak.
D) the tank circuits within the tuned amplifiers have too high a Q.

Underselectivity in a receiver means that its filter bandwidth is too wide, allowing it to pick up multiple stations on different frequencies simultaneously. This is because it cannot adequately discriminate between closely spaced signals.
