what causes sounds? A. electromagnectic energy B. the release of sensory neurons C. movement that causes changes in air placement D. vibrations that cause changes in air pressure

Option D

Vibrations that cause changes in air pressure

Explanation:

Sound is the disturbance or vibration of longitudinal mechanical waves which cause change in air pressure through a medium such as gas, liquid or solid. Therefore, what causes sound are these vibrations which subsequently cause changes in air pressure. When sound is transmitted and reflected, we call it pitch.
