In the quantum mechanical treatment of the hydrogen atom, which one of the following combinations of quantum numbers is not allowed?

a.) n=1; l=3; ml=0
b.) n=3; l=1; ml=-1
c.) n=3; l=2; ml=-1
d.) n=3; l=3; ml=2
e.) n=3; l=2; ml=2

I'm learning about the periodic tables and what each subject's configuration is. for example, hydrogen is 1s^1, but i don't understand how you get that. can someone me understand how to figure out how to figure this out? sorry if the question makes no sense, but it would really a lot if you could me understand! you so much if you can!
