(A) In a body-centered cubic $(BCC)$ unit cell,atoms are present at all the $8$ corners and one atom is present at the center of the body.Each corner atom contributes $1/8$ to the unit cell,so the contribution from $8$ corners is $8 	imes (1/8) = 1$ atom.The atom at the body center contributes $1$ fully to the unit cell.Therefore,the total number of atoms per unit cell = $1 + 1 = 2$.
