View answer and explanation

Correct option: C

{\mathrm{I}^ - },\mathrm{B}{\mathrm{r}^ - },\mathrm{C}{\mathrm{l}^ - },{\mathrm{F}^ - }

Option C (

{\mathrm{I}^ - },\mathrm{B}{\mathrm{r}^ - },\mathrm{C}{\mathrm{l}^ - },{\mathrm{F}^ - }

) is correct because polarizability increases with increasing size of the ion.
