Solution

The correct option is A Decrease in amplitude
The loudness of sound depends on amplitude. When amplitude increases loudness increases and vice versa. Here, since the volume is lowered, the amplitude of the wave decreases. The frequency here is unaffected due to the change in volume or amplitude.
