I'm not going to do your homework for you.
Draw the Lewis structures. A tetrahedral arrangement of electron pairs requires that there be four such pairs at the central atom. A "perfectly" tetrahedral molecular geometry -- and given the choices, I have to assume that whoever wrote the question defines "perfect" as meaning really truly perfect, with four identical bonds to four identical atoms -- requires that all four be bond pairs. So find the Lewis structure with four bonds to four identical atoms and no lone pairs.
