The statement "the equatorial diameter is 42 km greater than the polar diameter" is correct. This means that Earth is not perfectly spherical, but rather, it is slightly flattened at the poles and bulging at the equator. This shape is known as a "oblate spheroid." The statement in option A is incorrect because Earth is not elongated; it is actually nearly spherical in shape. Option B is also incorrect because Earth is the third largest planet in the solar system. Option D is incorrect because Earth is not perfectly spherical, as explained above. Option E is also incorrect because the correct term for Earth's shape is "oblate spheroid," not "prolate spheroid."
