Amplitude

Explanation:

The amount of energy a wave carries is determined by the amplitude. The larger the amplitude, the more energy the wave has, and the smaller the amplitude, the less energy the wave has.

In this case, since wave A has more energy than wave B, wave B must have a smaller amplitude than wave A.
