• A. Earth
• B. Mars
• C. Venus
• D. Jupiter

Hint:

Remember: Mercury is closest to the Sun, but Venus is the hottest due to the greenhouse effect—this is a common exam trap.

Answer 1

The Correct Option is C

Concept: The hottest planet is determined by its surface temperature, not its distance from the Sun. Step 1:Understand why Venus is hottest.
Although Mercury is closest to the Sun, Venus has a dense atmosphere rich in carbon dioxide, causing an extreme greenhouse effect.
Step 2:Effect of greenhouse gases.
The thick atmosphere traps heat, raising surface temperatures to about: \[ \sim 470^\circ \text{C} \]
Step 3:Eliminate incorrect options.}

• Earth $\rightarrow$ Moderate temperature
• Mars $\rightarrow$ Cold planet
• Jupiter $\rightarrow$ Gas giant, not hottest

Final Answer: \[ {\text{Venus}} \]
