Explanation: Although Mercury is the closest planet to the Sun, it does not have an atmosphere to trap heat. As a result, its temperature varies greatly between day and night.
Venus, on the other hand, has a thick atmosphere made of carbon dioxide, which causes an intense greenhouse effect, trapping heat and making it the hottest planet in the solar system.
The surface temperature of Venus can reach around 467°C (872°F), which is hotter than Mercury.
Other Options Explained:
(A) Mercury → Closest to the Sun but lacks an atmosphere to retain heat (~430°C in the daytime, but drops to -180°C at night).
(C) Mars → Much colder due to a thin atmosphere (~-63°C on average).
(D) Jupiter → A gas giant with no solid surface and much lower temperatures.
Thus, the correct answer is (B) Venus.
