Answer:
A. an increase in the height of the sound wave
Explanation:
Volume of the sound is measured by its intensity
So here we know that
intensity is directly depends on the square of the amplitude of the sound wave
so here as intensity depends on the loudness of the sound given as

so here as the loudness of sound will increase then the intensity will increase and hence the amplitude of the sound will also increase
So correct answer will be
A. an increase in the height of the sound wave
