• A. Mist
• B. Fog
• C. Haze
• D. Rainbow

Answer: (B)

Fog forms when a low, flat layer of cloud sits right at the Earth's surface, producing a visible blanket that reduces how far you can see. A stratus cloud near the ground is exactly that: a ground-hugging cloud. Mist is similar but less dense, so visibility stays relatively better. Haze comes from tiny particles in the air rather than a true cloud, and a rainbow is an optical effect from sunlight and raindrops, not a ground-level cloud. So the weather phenomenon described is fog.
