Which cloud commonly produces a halo about the Sun or Moon?

AI Explanation
The correct answer is C) Cirrostratus. Cirrostratus clouds, which are thin, sheet-like clouds composed of ice crystals, are the cloud type that commonly produces a halo around the sun or moon. This is because the ice crystals in cirrostratus clouds refract and reflect the light from the sun or moon, creating the characteristic halo effect. The other cloud types listed, altostratus, altocumulus, and cirrocumulus, do not typically produce halos around the sun or moon, as they have different cloud compositions and structures that do not exhibit the same light-refracting properties as cirrostratus clouds.
