The correct configuration of f-block elements is

A

(n−2)f1−14(n−1)d0−1ns2(n - 2)f^{1 - 14}(n - 1)d^{0 - 1}ns^{2}

B

(n−1)f1−14(n−1)d0−1ns2(n - 1)f^{1 - 14}(n - 1)d^{0 - 1}ns^{2}

C

(n−3)f1−14(n−2)d0−1(n−1)s2(n - 3)f^{1 - 14}(n - 2)d^{0 - 1}(n - 1)s^{2}

D

(n−2)f0−1(n−1)d0−1ns2(n - 2)f^{0 - 1}(n - 1)d^{0 - 1}ns^{2}

Answer

(n−2)f1−14(n−1)d0−1ns2(n - 2)f^{1 - 14}(n - 1)d^{0 - 1}ns^{2}
