Q: Answer-Which of the following metals is placed at the bottom of the reactivity series?

In chemistry, the reactivity series is a series of metals, in order of reactivity from highest to lowest. It is used to determine the products of single displacement reactions, whereby metal A will replace another metal B in a solution if A is higher in the series. Noble metals like gold, platinum are low in reactivity and are therefore kept at the bottom in the series. Hence, option A is correct.
