C Correct answer
Explanation

Venus is the hottest planet despite Mercury being closer to the Sun. Venus has an extremely dense atmosphere of carbon dioxide (96.5%) that creates an intense greenhouse effect, trapping heat and raising surface temperatures to about 465°C. Mercury has no atmosphere to retain heat, so its temperature drops drastically at night.
