Options
\[\ce{Cl}\]
\[\ce{Br}\]
\[\ce{F}\]
\[\ce{I}\]

Solution
\[\ce{F}\]
Explanation:
\[\ce{Cl, Br, I}\] all are having –1 to +7 oxidation state. But Oxidation state of \[\ce{F}\] is fixed (–1) as it is the most electronegative element and do not loose electron. Hence, it does not show disproportionate tendency.
