    Solution:

    Concept- During a chemical reaction, the substances that react are known as reactants whereas the substances that are formed during a chemical reaction are known as products.
    Each and every single displacement reaction listed in the alternatives is essentially an oxidation-reduction reaction. Based on our understanding of the different types of reactions, we can conclude that Ag cannot remove Fe from its salt solution because, in accordance with the electrochemical series, iron has a higher oxidation potential than Ag, which makes it easier for Fe to oxidise.
    Hence, option 1  is the correct answer.
