Current Loop as a Magnetic Dipole

An electron $(e)$ is revolving in a circular orbit of radius $r$ in hydrogen atom. The angular momentum of the electron is ( $M =$ magnetic dipole moment associated with it and $m =$ mass of electron)

Show answer and solution

Answer: (c)

Orbiting electron: $M = \frac{e}{2m}L$ .
$L = \frac{2mM}{e}$
So the answer is (c).
