Answer 1

Answer: 4

Complex	Hybridisation	Type
${\left[Co{F}_6\right]}^{3-}$	$s{p}^3{d}^2$	Outer orbital complex
${\left[Co{\left(N{H}_3\right)}_6\right]}^{3+}$	$d^{2}s{p}^3$	Inner orbital complex
${\left[Mn(CN{)}_6\right]}^{3-}$	$d^{2}s{p}^3$	Inner orbital complex
${\left[MnC{l}_6\right]}^{3-}$	$s{p}^3{d}^2$	Outer orbital complex
${\left[Co{\left(C_2{O}_4\right)}_3\right]}^{3-}$	$d^{2}s{p}^3$	Inner orbital complex
${\left[Fe(CN{)}_6\right]}^{3-}$	$d^{2}s{p}^3$	Inner orbital complex
