Nuts to the wording. Sonic booms are created when the aircraft is exceeding the speed of sound, for however long the speed exceeds the speed of sound.

A is so poorly worded, it is difficult to understand. I would go with B, but your teacher may argue that she meant A to be the answer, and mark you off.
