Correct Answer:
C. high
Explanation:
A higher pitch in sound is directly related to a higher frequency, which means a greater number of compressions and rarefactions pass through a specific point within a given timeframe. Since pitch is the brain's perception of frequency, an increase in the rate of these pressure variations results in a sound that is perceived as higher. Therefore, a high-pitched sound is characterized by more frequent vibrations compared to a low-pitched one.
