LIST-I contains metal species and LIST-II contains their properties. LIST-I LIST-II (I) [ {\Cr}( {\CN})_6]^{4-} (P) t_{2 {\g}} orbitals contain 4 electrons (II) [ {\RuCl}_6]^{2-} (Q) \mu (spin-only) =4.9 {\BM} (III) [ {\Cr}({\H}_2 {\O})_6]^{2+} (R) low spin complex ion (IV) [ {\Fe}( {\H}_2 {\O})_6]^{2+} (S) metal ion in 4+ oxidation state (T) d^4 species [Given : Atomic number of {\Cr}=24, {\Ru}=44, {\Fe}=26 ] Metal each metal species in LIST-I with their properties in LIST-II, and choose the correct option [JEE Adv 2022 P1]

Correct Answer is : (A) I → R, T; II → P, S; III → Q, T; IV → P, Q

(A) I \to R, T; II \to P, S; III \to Q, T; IV \to P, Q

(B) I \to R, S; II \to P, T; III \to P, Q; IV \to Q, T

(C) {\I} \to {\P}, {\R} ; {\II} \to {\R}, {\S} ; {\III} \to {\R}, {\T} ; {\IV} \to {\P}, {\T}

(D) I \to Q, T; II \to S, T; III \to P, T; IV \to Q, R
