    Quick Answer: "I"

    Explanation: Since you're forming an iconic bond, you want to get the total valance electrons to 8.

    Elements under 1A all have 1 valance electron, so all you really need to do is find an element with 7 electrons which under VIIIA column(7th column). The only elements in that 7th column are F, Cl, Br, I, and At. Therefore, I is the correct answer in this situation.

    Hopefully this helps you out! I tried my best to explain how I got the answer.
