The set of quantum numbers not applicable for an electron in an atom is

A

`n = 1, l = 1, m = 1, s = + 1//2 `

B

`n = 1, l =0, m = 0, s = + 1//2 `

C

`n = 1, l =0, m =0, s =-1//2`

D

` n = 2, l = 0, m = 0 , s = + 1//2`

Verified by Experts

When `n =1, l` can have only one value of that is zero. It cannot be one.
