(B) For an electron in an atom,the quantum numbers must satisfy the following rules:$1$. $n$ is a positive integer $(1, 2, 3, \dots)$.$2$. $l$ can have values from $0$ to $(n - 1)$.$3$. $m$ can have values from $-l$ to $+l$ (including $0$).$4$. $s$ can be $+1/2$ or $-1/2$.In option $B$,$n = 3$ and $l = 2$. The allowed values for $m$ are $-2, -1, 0, +1, +2$. Since $m = -3$ is outside this range,this arrangement is not permissible.
