4. A cell with a selectively permeable membrane is in a solution. Urea can diffuse through the membrane (by passive diffusion in either direction) but ions such as Na+, Cl- and K+ cannot. Which of the following is correct? Urea Urea K Urea K* Inside of cell Naci Urea K K* NaCl K NaCl Urea Urea Urea Urea Solution Urea Naci Urea K K+ Selectively permeable Urea K NaCl K Urea NaCl K* Urea NaCl K non-penetrating Naci non-penetrating Urea penetrating membrane A. The solution is hypoosmotic and hypotonic relative to the cell, and the net movement of water is towards the cell B. The solution is hyperosmotic and hypotonic relative to the cell, and the net movement of water is towards the cell C. The solution is isoosmotic and isotonic relative to the cell, and the net movement of water is null D. The solution is hypoosmotic and hypertonic relative to the cell, and the net movement of water is towards the solution E. The solution is isoosmotic and hypertonic relative to the cell, and the net movement of water is towards the solution
