A third-order rate constant has units of concentration^{-2} time^{-1}. In option D, the units are L mol^{-1} s^{-1}, which when raised to the power of 3 (to match the order of the rate constant) become L^3 mol^{-3} s^{-3}, which is equivalent to concentration^{-2} time^{-1}. Therefore, option D is the best choice.
