Match List-I with List-II.

List-I (Complex)		List-II (Hybridization & Magnetic characters)
(A)	[MnBr4]2–	(I)	d2sp3 & diamagnetic
(B)	[FeF6]3–	(II)	sp3d2 & paramagnetic
(C)	[Co(C2O4)3]3–	(III)	sp3 & diamagnetic
(D)	[Ni(CO)4]	(IV)	sp3 & paramagnetic

Choose the correct answer from the options given below :

$$\begin{gathered} \text{(A)}{\left[{\mathrm{MnBr}}_4\right]}^{2-} \\ {\mathrm{Mn}}^{+2}\Rightarrow \left[\mathrm{Ar}\right]3{\mathrm{d}}^5 \end{gathered}$$

In presence of ligand field

$\Rightarrow {\mathrm{sp}}^3$hybridization, paramagnetic in nature

$$\begin{gathered} \text{(B)}{\left[{\mathrm{FeF}}_6\right]}^{3-} \\ {\mathrm{Fe}}^{+3}\Rightarrow \left[\mathrm{Ar}\right]3{\mathrm{d}}^5 \end{gathered}$$

In presence of ligand field

$\Rightarrow {\mathrm{sp}}^3{\mathrm{d}}^2$hybridization, paramagnetic in nature

$$\begin{gathered} \text{(C)}{\left[\mathrm{Co}{\left({\mathrm{C}}_2{\mathrm{O}}_4\right)}_3\right]}^{3-} \\ {\mathrm{Co}}^{+3}\Rightarrow \left[\mathrm{Ar}\right]3{\mathrm{d}}^6 \end{gathered}$$

In presence of ligand field

$\Rightarrow {\mathrm{d}}^2{\mathrm{sp}}^3$hybridization, diamagnetic in nature

$$\begin{gathered} \text{(D)}\left[\mathrm{Ni}\right(\mathrm{CO}{)}_4] \\ {\mathrm{Ni}}^0\Rightarrow \left[\mathrm{Ar}\right]3{\mathrm{d}}^{8}4{\mathrm{s}}^2 \end{gathered}$$

In presence of ligand field

$\Rightarrow {\mathrm{sp}}^3$hybridization, diamagnetic in nature
