(D) In facilitated diffusion,some carrier proteins allow transport only if two types of molecules move together.$1$. In $Symport$,both molecules cross the membrane in the same direction.$2$. In $Antiport$,the molecules move in opposite directions.$3$. In $Uniport$,a molecule moves across a membrane independent of other molecules.Therefore,$A$ represents $Symport$ and $B$ represents $Antiport$.
