D

Answer to Question 2

Both have solid inner cores and outer fluid cores. The Moon has less iron, probably due to the source of its material being primarily the Earth's crust. Mercury's core is very large due to the temperature of that part of the solar system when Mercury formed. The process of differentiation led to the higher density material sinking to the center of these bodies.
