B Correct answer
Explanation

Mars appears red because its surface is covered with iron oxide (rust), which gives the planet its characteristic reddish-orange appearance. This iron oxide is abundant in Martian soil and rocks. Mars is not hot enough to be a fireball, doesn't have red water, and while the sun does heat it, the heat doesn't create the red color.
