The diagram below shows a tank system consisting of 3 compartments (A, B and C) and 2 membranes (Xand Y) set up to study osmolarity and tonicity. The membrane permeabilities are shown in the table.Compartment A is filled with a solution of 300 mM Sucrose. Compartment B is filled with a solution of100 mM CaCl, Compartment C has a solution of 300 mM Urea.

A phospholipid bilayer separates two chambers. The chambers both contain the same volume of water. The left chamber contains 150 mM of an unknown solute A. Solute B is dissolved in the right chamber also at a concentration of 150 mM. Therefore, the initial osmolarity is the same (isotonic) between the two chambers. However, after a short time, the volume increases substantially in the right chamber. What is the most likely ranking of permeability for the molecules to cause this change? (greater permeability means that the molecule moves first across the membrane)
