$X Y$ is the membrane/partition between two chambers 1 and 2 containing sugar solutions of concentration $c_1$ and $c_2\left(c_1>c_2\right) \mathrm{mol} \mathrm{L}^{-1}$. 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, $\mathrm{p}_1\gt \pi$ B. Membrane/Partition : Porous, $\mathrm{p}_2\gt \pi$ C. Membrane/Partition : Parchment paper, $p_1\gt \pi$ D. Membrane/Partition : Cellophane, $\mathrm{p}_2\gt \pi$ Choose the correct answer from the option given below:
