B)mirages
C)chromatic aberration
D)light scattering

When rays coming from an object are not reasonably close to the optic axis, spherical aberration occurs. This happens when the light rays that pass through the edges of the lens or mirror are focused differently than those passing through the center, resulting in blurry images. Mirages are caused by the refraction of light in a different medium, chromatic aberration is caused by the dispersion of light, and light scattering occurs when light is dispersed in different directions due to irregularities in the medium.
