Answer:

A, because it has a lower amplitude

Step-by-step explanation:

Energy of wave is represented in the formula:

e = 1/2kA^2

where:

---> k is constant

---> a is amplitude

hence, the increase or decrease of energy depends on the amplitude of the wave

if the amplitude is less, than the energy is also less.
