Medium$A$ magnetic dipole experiences a torque of $80 \sqrt{3} \ N \ m$ when placed in a uniform magnetic field in such a way that the dipole moment makes an angle of $60^{\circ}$ with the magnetic field. The potential energy of the dipole is
- A$80 \ J$
- B$-40 \sqrt{3} \ J$
- C$-60 \ J$
- D$-80 \ J$
