Based on Crystal Field theory, match the Complex ions listed in Column I with the electronic configuration in the d orbitals of the central metal ion listed in Column II.

No.	Complexion	No.	d orbital configuration of central metal ion.
(A)	$$ \left[M n(C N)_6\right]^{4-} $$	(P)	$$ e_g^2 t_{2 g}^3 $$
(B)	$$ \left[\mathrm{Co}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right]^{2+} $$	(Q)	$$ t_{2 g}^4 e_g^2 $$
(C)	$$ \left[\mathrm{Fe}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right]^{2+} $$	(R)	$$ t_{2 g}^5 $$
(D)	$$ \left[\mathrm{MnCl}_4\right]^{2-} $$	(S)	$$ t_{2 g}^5 e_g^2 $$

$$ \mathrm{A}=\mathrm{S} \quad \mathrm{B}=\mathrm{R} \quad \mathrm{C}=\mathrm{P} \quad \mathrm{D}=\mathrm{Q} $$

$$ \mathrm{A}=\mathrm{R} \quad \mathrm{B}=\mathrm{S} \quad \mathrm{C}=\mathrm{Q} \quad \mathrm{D}=\mathrm{P} $$

$$ \mathrm{A}=\mathrm{Q} \quad \mathrm{B}=\mathrm{S} \quad \mathrm{C}=\mathrm{P} \quad \mathrm{D}=\mathrm{R} $$

$$ \mathrm{A}=\mathrm{R} \quad \mathrm{B}=\mathrm{S} \quad \mathrm{C}=\mathrm{P} \quad \mathrm{D}=\mathrm{Q} $$
