C
$1{s^2},\;2{s^2}2{p^6},\;3{s^2},\;3{p^6}3{d^{10}},\;4{s^2}4{p^2}$
D
$1{s^2},\;2{s^2}2{p^6},\;3{s^2},\;3{p^6}3{d^{10}},\;4{s^2}4{p^1}$

✓

Answer

Correct option: B.

$1{s^2},\;2{s^2}2{p^6},\;3{s^2},\;3{p^6}3{d^2},\;4{s^2}$

b
(b)We know that transition element are those element which have partially filled $ d-$ subshell in their elementary form. Therefore, the general electronic configuration of $ d-$ block element is $(n - 1)\;{d^{1 - 10}}n{s^{1 - 2}}$.
