Question

mercury is the _______ planet.
reddest
hottest
smallest

Explanation:

To solve this, we analyze each option:

• "reddest": Mars is known as the reddest planet, not Mercury.
• "hottest": Venus is the hottest planet due to its thick atmosphere, not Mercury.
• "smallest": Mercury is the smallest planet in our solar system.
• "Largest": Jupiter is the largest planet.

So the correct description for Mercury is "smallest".
