XY is the membrane/partition between two chambers 1 and 2 containing sugar solutions of concentration ${{\rm{c}}_1}$ and ${{\rm{c}}_2}\left( {{{\rm{c}}_1} > {{\rm{c}}_2}} \right){\rm{mol}}{{\rm{L}}^{ - 1}}$ . 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, ${{\rm{p}}_1} > \pi $
B. Membrane/Partition : Porous, ${{\rm{p}}_2} > \pi $
C. Membrane/Partition : Parchment paper, ${{\rm{p}}_1} > \pi $
D. Membrane/Partition : Cellophane, ${{\rm{p}}_2} > \pi $
