in diffuse reflection,
the light hits a bumpy surface and bounces back at many different angles.
the light hits a smooth surface and bounces back at right angles.
the light hits a smooth surface and bounces back at many different angles.
the light hits a bumpy surface and bounces back at right angles.

Explanation:

Diffuse reflection occurs when light hits a rough (bumpy) surface. The irregularities of the surface cause the light rays to bounce back in many different directions. In contrast, specular reflection happens on smooth surfaces where light reflects at the same angle as the incident angle. For smooth surfaces, light doesn't bounce back at many different angles or just at right - angles in the context of diffuse reflection.

Answer:

The light hits a bumpy surface and bounces back at many different angles.
