D Correct answer
Explanation

The moon's density is about 3.34 g/cm³, while Earth's average density is about 5.51 g/cm³. This difference exists because the moon lacks Earth's large iron core. Option A is incorrect - the densities differ significantly, and B/C are wrong as the moon is LESS dense, not more.
