Answer 1

The correct option is A

pitch

1. Shrillness is the quality of sound that depends on its pitch.
2. The pitch of the sound depends on the frequency of vibration of the waves.
3. If the frequency of vibration is higher, we say that the sound is shrill and has a high pitch.
4. If the frequency of vibration is lower, we say that the sound is grave and has a low pitch.
5. Hence, option (a) pitch is correct.
