Answer 1

The Correct Option is A

Step 1: Understanding the term "Blue Planet."
The term "Blue Planet" refers to Earth due to its appearance from space. Earth's surface is mostly covered by water, which gives it a blue appearance when seen from a distance in space.

Step 2: Explanation of other options.
- Mars (Option 2) is known as the "Red Planet" due to its reddish appearance caused by iron oxide on its surface.
