Hint: The element which is less reactive than chlorine can be easily removed by chlorine. From the above options chlorine can remove bromine from sodium bromide solution due to more reactivity.
Complete Step by Step Answer:
Chlorine is more reactive than bromine but less reactive than fluorine so, it can easily remove bromine from sodium bromide solution. Chlorine gas reacts with the salt of bromine that is sodium bromide to produce a salt of chlorine that is sodium chloride along with bromine gas as products. The reaction can be given as follows:
$C{{l}_{2}}+2NaBr\to 2NaCl+B{{r}_{2}}$
Thus in this reaction one mole of Chlorine gas reacts with two moles of the salt of bromine that is sodium bromide to produce two moles of a salt of chlorine that is sodium chloride along with one mole of bromine gas as products.
As the fluorine is more reactive than chlorine so, chlorine cannot remove fluorine from sodium fluoride and calcium fluoride solutions. Thus we can write that chlorine can remove bromine gas from sodium bromide solution.
Thus the correct option is A.
Note: Chlorine is a group $17$ element. It is also known as halogen element. It generally exists as a gas at room temperature. It is a greenish-yellow colored gas and has the atomic number of $17$. It is more reactive than bromine but less reactive than fluorine among halogens.. Due to the least reactivity of iodine, itcan not replace any other halogen.
