The correct answer is:

C. A reflected sound wave bounces back to the place of origin. A diffracted sound wave changes direction as it passes through an opening.

In summary:

  • Reflection involves a sound wave bouncing back after hitting a surface.
  • Diffraction involves a sound wave bending or spreading out as it passes through an opening or around obstacles.
