Verified by Experts
The correct answer is:
D

As the size of anion increases the distance between the nucleus and valence shell electrons increases resulting into weak force of attraction between them. This leads to increase in the ease of the donation of electrons in the order F – < Cl – < Br – < I – . Hence I – acts as a strongest reducing agent.
