C, D, A, B With clear explanations plz

Metals deform along planes of atoms that are most tightly packed together, i.e., most densely packed planes in close-packed directions. c. Draw a sketch of the (111) plane of the FCC unit cell. Are these atoms close-packed? d. Draw a sketch of the close-packed plane in HCP unit cell. It will be simply an atom surrounded by 6 others in the plane. 3) Comparing FCC and HCP structures: a. Is there a difference in packing (coordination number) between these two types of structure? b. Look at the two structures. A small difference in the arrangement of atoms causes a dramatic difference in the properties of FCC ductile metals and HCP brittle metals. Can you see it? Try to draw the differences (You can draw the 3-layers separately)
