(B) In a $BCC$ (Body-Centered Cubic) unit cell,the number of atoms per unit cell is $1 + (8 \times \frac{1}{8}) = 2$. In an $FCC$ (Face-Centered Cubic) unit cell,the number of atoms per unit cell is $(8 \times \frac{1}{8}) + (6 \times \frac{1}{2}) = 1 + 3 = 4$. Therefore,the number of atoms per unit cell for $BCC$ and $FCC$ are $2$ and $4$ respectively.
