Answer:

Answer choice B.

Step-by-step explanation:

Comets are usually made up of ice, dust, and gas, meaning that options A and D are wrong. Also, as a comet approaches the sun, its particles heat up so quickly that they don't have time to become liquid; they turn straight from solid to gas. This makes them very visible when they come near the sun. Therefore, the correct answer is B. Hope this helps!
