Given that n = 2 for an electron configuration, the following stationary state is not permitted:
A) n = 2, $l$ = 2, m = 1.
B) n = 2, $l$ = 1, m = 0.
C) n = 2, $l$ = 1, m = 1.
D) Hold on. All of the above states are permitted.

For a given value of n (principal quantum number), the possible values of $l$ (azimuthal quantum number) range from 0 to $n-1$. Therefore, for $n = 2$, $l$ can only be 0 or 1. The option A with $l = 2$ is not permitted because it exceeds the maximum value $l$ can have for $n = 2$.
