XY is the membrane/partition between two chambers 1 and 2 containing sugar solutions of concentration $$c_1$$ and $$c_2$$ ($$c_1 \gt c_2$$) mol $$L^{-1}$$. For the reverse osmosis to take place identify the correct condition. (Here $$p_1$$ and $$p_2$$ are pressures applied on chamber 1 and 2)

(A) Membrane/Partition ; Cellophane, $$p_{1} > \pi$$
(B) Membrane/Partition ; Porous.$$p_{2} > \pi$$
(C) Membrane/Partition ; Parchment paper, $$p_{1} > \pi$$
(D) Membrane/Partition : Cellophane, $$p_{2} > \pi$$
