Explanation:

The spin quantum number is introduced to account for the anomalous Zeeman effect or the splitting of emission lines into more lines than given by the magnetic quantum number. This effect is observed when a magnetic field is applied to an atom, causing the energy levels to split into sub-levels. The splitting of lines is not just dependent on the magnetic quantum number, but also on the spin of the electron.

The spin of an electron is represented by two arrows: (spin up) and (spin down). This means that the electron can have two possible spin states. The spin quantum number is denoted by the symbol 's' and can have a value of either +1/2 or -1/2.

When a magnetic field is applied to an atom, the energy levels split into sub-levels. The number of sub-levels is given by 2s+1, where 's' is the spin quantum number. This means that an electron with a spin quantum number of +1/2 or -1/2 can have two sub-levels.

The anomalous Zeeman effect occurs because the magnetic field affects the energy levels differently depending on the electron's spin. Electrons with spin up are affected differently than electrons with spin down. This causes the energy levels to split into more lines than given by the magnetic quantum number alone.

Conclusion:

Therefore, the spin quantum number is introduced to account for the anomalous Zeeman effect or the splitting of emission lines into more lines than given by the magnetic quantum number.

In anomalous Zeeman effect the splitting of spectral lines occurs due to interaction of the applied magnetic field with the magnetic moment generated by the orbital and 'spin' motions of the electron. and hence b) is the answer!
