Solution

The correct option is B $K_{2} C r O_{4}$
The oxidation state of $C r$ in different compounds are

$C r C l_{3}$ ----- +3

$C r F_{3}$ ------ +3

$C r_{2} O_{3}$ ------ +3

$K_{2} C r O_{4}$ -------+6

As oxidation state of $C r$ is maximum (maximum positive charge) in $K_{2} C r O_{4}$ so ionic radii of $C r$ is minimum here.
