C Correct answer
Explanation

The pitch or shrillness of a sound depends primarily on its frequency - higher frequencies produce higher-pitched sounds, while lower frequencies produce lower-pitched sounds. Amplitude affects the loudness or intensity of sound, not its pitch. While wavelength is inversely related to frequency, pitch perception is directly tied to frequency.
