well i would say D

Explanation:

the crust in fact does have more iron within in it but if i describe it more i would say the crust is a smaller amount then the mantle, and that its a bit harder material then the mantle itself

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

it is stable as it is in group 0 which have full outer shells of electrons
