Solution

The correct option is C the spin angular momentum of electrons
Fine structure of hydrogen spectrum is explained by spin angular momentum of electrons whereas, orbital angular momentum, finite size of nucleus or the presence of neutrons in the nucleus does not explain the fine structure of hydrogen spectrum.
