Let’s check the given characteristics and find the one which isn’t similar between Earth and Moon:1.Both do not give off light of their own ----- Correct. Earth is a planet. Moon is a natural satellite of Earth. They do not give off light of their own. Only stars give off light of their own.2.Both are round in shape ----- Incorrect. Since the Earth is flattened at the poles and bulges at the Equator, its shape appears to be oblate spheroid. This is because the Earth rotates on its shorter axis. Moon is also oblate spheroid, meaning it has the shape of a ball that is slightly flattened.3. Both are Sun's satellite ----- Incorrect. A satellite is anything that orbits around a larger object. Earth is a satellite of Sun because it revolves around the sun. But Moon is the satellite of Earth, not Sun, because it orbits around the Earth.4. Both have gravitational pull ----- Correct. Both Earth and Moon have gravitational pull, though Earth’s gravitational pull is 6 times greater than Moon’s.This shows Only Statements 2 and 3 are correct. Hence, the right answer is Option B.

Srivasta, you are wrong. The answer would be B because the earth isn't round. It is geoid in shape i.e flattened from the poles and bulge in the middle. This answer is also justified as the earth is not the sun's satellite.
