detailed solution

Correct option is B

The quantum numbers represent the orbitals being filled in the ground state for the elements $Sc$ (21) to $Zn$ (30) is $n = 3, l = 2$ .

$S_{C_{21}} = [A s] 3 d^{1} 4 s^{2}$

${Z_{n}}_{30} = [A s] 3 d^{10} 4 s^{2}$

$3 d$ subshell is filled,

$S = 0$ , $P = 1$ , $(d = 2)$

$n = 3, l = 2$

Hence, the option B is correct.
