(B) The electronic configuration is $1s^2 2s^2 2p^3$. For $n = 2$ and $l = 1$,the electrons are in the $2p$ subshell. The $2p$ subshell has $3$ orbitals $(p_x, p_y, p_z)$ containing $3$ electrons. According to Hund's rule,these $3$ electrons will occupy separate orbitals with parallel spins. Thus,all $3$ electrons in the $2p$ subshell can have a spin quantum number $s = +1/2$.
