Potassium, because ionic compounds are formed with a metal and non-metal, Fluorine is a non metal but only Potassium is a metal of the list provided.

Ionic compound is when a metal combines with a non-metal or a metalloid. Since fluorine is a non-metal, we need a metal in order to form an ionic compound. Thus potassium is the answer.
Hope this would help :))
