Solution

The correct option is B high, low
Pitch depends upon the frequency of sound waves.
  • If the frequency is high then the pitch will be high and vice-versa.
  • As the frequency or pitch of the sound increases, the sound gets sharper and shriller like that of a child crying or a girl screaming.
  • Similarly, sounds of a bass drum and rumbling have low frequency or pitch and are called dull sounds.
Thus, we can say that, a shrill sound has a high pitch and a dull sound has a low pitch.
