Answer: c

Explanation: I passed the test and got this answer right

When the sound gets louder so here the standing wave should be produced.

What is a standing wave?

The standing wave refers to the stationary wave that combined the two waves that should be moved in the inverse directions and contain the similar kind of the amplitude and the frequency.

Also, it leads to the interference where the waves should be superimposed and the energies should be added or canceled out.

Therefore, the third option is correct.
