D. Physical properties. The arrangement of atoms determines the electronegativity, the valence, the melting and boiling point and many other factors.

In my opinion, the best answer among the choices given is option D. The physical properties of a mineral is determined by the type and arrangement of atoms in a mineral. Colors, crystal form, hardness, luster and many other properties of a mineral are dictated by the arrangement of the atoms and the bonds present.
