Hint: Among the halogens iodine is least electronegative and least reactive element. It is less reactive than chlorine, fluorine and bromine.
Complete Step by Step Answer:
Iodine is less reactive so, when the mixture of sodium chloride, sodium bromide and sodium fluoride is treated with iodine gas no reaction takes place and no products are formed. If this mixture is treated with chlorine gas then bromine gas is formed as chlorine is more reactive than bromine so, it can easily remove bromine gas.
Thus the correct option is D.
Additional Information: Iodine is a halogen element. It has the symbol of $I$. It generally exists as a gas. It has the colour of violet blue. Iodine is generally obtained from seaweed. Starch generally acts as an indicator in titration reactions to determine the end point of a titration. Iodine gas reacts with starch, an indicator gives blue colour.
Note: Iodine is less reactive among the halogens and fluorine is the most reactive among the halogen as fluorine has the highest electronegativity and smallest size. Fluorine can easily displace any other halogen from their respective salts.
