I think the correct answer from the choices listed above is option A. CHCl3 most likely would be the polar compound. Two of the chlorine atoms that are opposite each other will cancel their pull, but the chlorine that is opposite to the hydrogen will pull more and the molecule will have a dipole in the direction of chlorine since the pull is not sufficiently offset by the hydrogen.
