remember, ionic is when you have a metal with a nonmetal. covalent is two nonmetal together.  most periodic table show that "staircase" on the right side that show where metals and nonmetal are; in any case, I attached a periodic table showing this. 

a. KF--> K is metal, F is nonmental, so this is ionic

the rest of the choices are two nonmetals together.
