D Correct answer
Explanation

Wavelength is defined as the distance between two consecutive crests or troughs of a wave. It represents the spatial period of the wave. Loudness is related to amplitude, frequency is the number of wave cycles per second, and amplitude is the maximum displacement from equilibrium.
