Solution
The correct option is D Simple cubic unit cell
Square packed layers/sheets are placed exactly above one another to get 3-D closed packing. Here, arrangement of spheres is perfectly aligned horizontally as well as vertically. The formed lattice has AAA type arrangement where, A is any layer in the packing.
Lattice thus generated is simple cubic lattice and its unit cell is simple cubic unit cell.
Thus, option (a) and (d) are correct.
