Solution

The correct option is D $[F e F_{6}]^{3 -}$
$[F e F_{6}]^{3 -}$ has electrons that are symmetrically filled in both $t_{2 g}$ and $e_{g}$ orbitals.
F is a weak ligand. Hence, the complex will be high spin complex.

Fe(III) has $3 d^{5}$ as the outer electronic configuration which can also be written as $t_{2 g}^{3} e_{g}^{2}$ .
