B Correct answer
Explanation

Venus is the hottest planet in our solar system with surface temperatures reaching about 465°C (869°F), despite Mercury being closer to the Sun. This extreme heat is caused by Venus's thick atmosphere of carbon dioxide, which creates a runaway greenhouse effect that traps solar radiation. Mercury's lack of atmosphere means it can't retain heat as effectively.
