The four quantum numbers, the principal quantum number (n. the angular momentum quantum number (t), the magnetic quantum number (m), andthe spin quantum number (ms) have strict rules which gavemthe possible values.

The first three quantum numbers (n,l,ml) are all related to one another
n can be any number grater than zero
l can be 0 to n-1
ml can be -l to l
ms can only be +1/2 or -1/2
A set of legitimate quantum numbers satisfies all those criteria
a) wrong because n =6 = l where it should be n-1
b) wrong because n = 3 and l = n-1 = 2
c) wrong because n = 4 and l = n-1 = 2
d) correct because n = 5 , l = 5-1 = 4 ,ml is between -l to l
e) wrong because n =3 and l = -1 which is not possible as l cannot be negative where it should be n-1
f) wrong as because ms is not 1/2 or -1/2 which is =-1 given
