Vedclass · Answer

(C) The correct answer is $(C)$.As we move down the group in halogens,the atomic size increases due to the addition of new shells.As the atomic size increases,the distance between the nucleus and the valence electrons increases,leading to a decrease in the effective nuclear attraction.Consequently,the energy required to remove an electron,known as the ionization potential,decreases.
