Explanation:

2nd, 3rd and 4th statements are incorrect.
3rd statement is incorrect because Venus is called Earth's twin.
Mars is approximately half the diameter of Earth with a surface area only slightly less than the total area of Earth's dry land. Mars is less dense than Earth, having about 15% of Earth's volume and 11% of Earth's mass, resulting in about 38% of Earth's surface gravity.
