Answer: The correct answer is Option A.

Step-by-step explanation:

For the given options:

Option A: Amplitude of a wave is defined as the maximum distance from its mean position. It tells us about the loudness of the wave and also the sound energy.

Option B: Rarefaction is defined as the region which is low in density.

Option C: Speed of the wave is defined as product of the wave's frequency and wavelength.

Option D: Wavelength is defined as the distance between two crests or two troughs.

Hence, the correct answer is Option A.
