Vedclass · Answer

(B) For an electron in a $3d$ orbital,the principal quantum number $n$ is $3$.For a $d$ subshell,the azimuthal quantum number $l$ is always $2$.The magnetic quantum number $m_l$ can take any integer value from $-l$ to $+l$,which means $m_l \in \{-2, -1, 0, +1, +2\}$.The spin quantum number $m_s$ can be either $+1/2$ or $-1/2$.Comparing these requirements with the given options,option $B$ $(n=3, l=2, m_l=+2, m_s=-1/2)$ satisfies all these conditions.
