As learnt in

Magnetic Quantum Number (m) -

 For any sub-shell (defined by ‘l ’value) 2\: l+1values of m are possible and these values are given by :

m = – l , – ( l –1), – ( l – 2)... 0,1... ( l – 2), ( l –1),l

-

 

 For any subshell, the no. of possible values of magnetic quantum number are 2l+1. In other words, the no. of orbitals are 2l+1.
So, no. of electrons = 2\times no. of orbitals

                               = 4l+2


Option 1)

2l+1

This solution is incorrect

Option 2)

4l-2

This solution is incorrect

Option 3)

2n^{2}

This solution is incorrect

Option 4)

4l+2

This solution is correct
