Question

Quizplus · Accepted Answer

Comets are small objects made up of ice, dust, and rock. When a comet approaches the Sun, its surface begins to warm up and the ice starts to vaporize into gas. This process releases dust particles that are carried away from the comet by the solar wind, creating a long, visible tail that can extend for thousands of kilometers behind the comet. Therefore, choice B is the best option.
