Correct Option: C

An oxidizing agent is a chemical species that removes an electron from another species. Fluorine, having the largest positive value of electrode potential, is the strongest oxidizing agent. As a matter of fact, all halogens have a tendency to take up electrons and thus act as strong oxidizing agents. Among them, Fluorine (the most electronegative element) is given a value of 4.0 and is the strongest oxidizing agent which is reflected in its highly positive standard potential (Eo = +2.85 V). The oxidizing power decreases from fluorine to iodine. Fluorine is so strong an oxidizing agent that it is impossible to carry out reactions with it in aqueous solution. 2F₂+H₂O ⇒ 4HF+O₂
