(B) For the complex $[CoF_6]^{3-}$:$1$. The coordination number is $6$,so it has an octahedral geometry. Statement $I$ is true.$2$. The oxidation state of $Co$ is $x + 6(-1) = -3$,which gives $x = +3$. The coordination number is $6$. Statement $II$ is false.$3$. $F^-$ is a weak field ligand,so it forms an outer orbital complex with $sp^3d^2$ hybridization. Statement $III$ is true.$4$. Since it is an outer orbital complex with weak field ligands,it remains a high spin complex. Statement $IV$ is true.Therefore,statements $I$,$III$,and $IV$ are correct.

List-$I$	List-$II$
$A. K_2[Ni(CN)_4]$	$I. sp^3$
$B. [Ni(CO)_4]$	$II. sp^3d^2$
$C. [Co(NH_3)_6]Cl_3$	$III. dsp^2$
$D. Na_3[CoF_6]$	$IV. d^2sp^3$

List-$I$ (Complexes)	List-$II$ (Hybridisation)
$A$. $[Ni(CO)_4]$	$I$. $sp^3$
$B$. $[Cu(NH_3)_4]^{2+}$	$II$. $dsp^2$
$C$. $[Fe(NH_3)_6]^{2+}$	$III$. $sp^3d^2$
$D$. $[Fe(H_2O)_6]^{2+}$	$IV$. $d^2sp^3$
