Best answer
Correct choice is (c) Earth

Easiest explanation: About 71% of the earth’s surface is covered in water, which appears blue from space. Earth is known as blue planet because of its blue visibility when we see it from outer space. No other planet is having such a large amount of water this is also the reason for its blue color.
