Correct option is (a) Fluorine’s reactivity is greater than that of bromine

To explain: The order of reactivity of halogens with hydrogen is that Fluorine’s reactivity is greater than that of chlorine and chlorine’s reactivity is greater than that of bromine and bromine’s reactivity is greater than that of Iodine.
