Best answer
Right choice is (d) Am^2

The best explanation: The magnetic dipole moment of a magnetic dipole is defined as the product of its pole strength and magnetic length. The SI unit of magnetic dipole moment is ampere metre^2 (Am^2). Magnetic dipole moment is a vector quantity and is directed from south to north pole of the magnet.
