Answer 2

Answer: Option (a) Cu, Fe, Zn, AI is the correct option.

Explanation:

Copper (Cu) , Iron (Fe) , Zinc (Zn) and Aluminum (Al) is the correct sequence according to increasing reactivity. Copper is less reactive as compared to Iron, Zinc and Aluminum while in the order Aluminum is highly reactive. Reactivity depends upon the position of the metal in emf series. Aluminum is placed lower in emf series that's why it is more reactive.
