(A) In a primitive cubic unit cell,atoms are present only at the corners of the cube.Each corner atom is shared by $8$ adjacent unit cells.Therefore,the contribution of each corner atom to a single unit cell is $\frac{1}{8}$.$A$ cube has $8$ corners.Total number of atoms per unit cell = $8 	imes \frac{1}{8} = 1$.
