Which of the following orbitals can not exist?

Which of the following orbitals can not exist:

A. 2p

B. 3d

C. 5d

D. 3f

E. 160p

The first quantum number is n, principle energy level, and n can be any integer 1 2 3 and so on.

The next quantum number is l and l has a rule that depends on n. l has to go from 0 to n minus 1. For example if n=3, l =0,1,2.

L is also represented by letters. When l=0=s, l=1=p, l=2=d, l=3=f

Choice D is wrong since n=3 and l=3=f. l can not equal to 3 since if n=3, the possible values for l are 0,1 or 2.
