The correct answer is option d, that is, Zn + H₂SO₄ → ZnSO₄ + H₂
A single displacement reaction refers to a kind of chemical reaction in which one element substitutes another element in a chemical reaction. The more reactive element will substitute the less reactive element. This is illustrated with the help of reactivity series, as the metal that is present above in the series will substitute the metal that is present below in the series readily. From the given equations, Zn + H₂SO₄ → ZnSO₄ + H₂ is a kind of single displacement reaction.

So basically, the change in color effects the amount of cations in the solution making it a physical change rather than a chemical one, defying the law of conservation of mass! I hope this helped! (The only time the change in color affects the amount of cations is in the Alkaline Earth Metals)
