The Earth's average density (5520 kg/m3) is slightly higher than that of Mercury (5430 kg/m3).  This is because
A)   the Earth has a larger iron core in proportion to its size than Mercury has.
B)   the Earth is more massive than Mercury and has therefore become more compressed, gravitationally.
C)   Mercury's interior has expanded slightly because of radioactive heating, thereby reducing its density since its formation.
D)   the Earth has a denser atmosphere than Mercury has.
