  • C. Vibrate but not in a certain direction
  • D. The waves vibrate perpendicular to the direction of propagation
Correct Answer: Option A - When the sound passes through the air, the air particles vibrate in the direction of wave propagation. Sound is a mechanical wave that requires a medium for transmission.
