In hexagonal close packing of spheres in three-dimensions

Question

In hexagonal close packing of spheres in three-dimensions (A) in one unit cell there are 12 octahedral voids and all are completely inside the unit cell (B) in one unit cell there are six octahedral voids and all are completely inside the unit cell (C) in one unit cell there are six octahedral voids out of which three are completely inside the unit cell and other three are from contributions of octahedral voids which are partially inside the unit cell (D) in one unit cell there are 12 tetrahedral voids, all are completely inside the unit cell.

In hexagonal close packing of sphere in three dimensions. In one unit cell there are 6- octahedral voids and 12 - tetrahedral voids.

Q. In hexagonal close packing of spheres in three-dimensions

in one unit cell there are $12$ octahedral voids and all are completely inside the unit cell

in one unit cell there are six octahedral voids and all are completely inside the unit cell

in one unit cell there are six octahedral voids out of which three are completely inside the unit cell and other three are from contributions of octahedral voids which are partially inside the unit cell

in one unit cell there are $12$ tetrahedral voids, all are completely inside the unit cell.

In hexagonal close packing of sphere in three dimensions. In one unit cell there are $6 -$ octahedral voids and 12 - tetrahedral voids.
