Best answer
Right choice is (a) ratio of magnetic moment to angular momentum

The explanation: The angular frequency (Larmor frequency) of this precession is given by:

W = 2p v = r Bo

Where r is the ratio of the magnetic moment to the angular momentum (the magnetic gyro ratio) and Bo is the density of the steady magnetic field and v is the frequency of radiation.
