What is visking tubing?

The containers $\mathrm{X}$ and $\mathrm{Y}$ have $1$ litre of pure water and $1$ litre of $0.1 \mathrm{M}$ sugar solution, respectively. Which one of the following statements would be correct regarding their water potential $\left(\mathrm{\Psi }\right)$ and osmotic potential $\left(\mathrm{\Psi }s\right)?$

*Note: There were errors in original KVPY papers, and thus the options are modified here.

Assertion ($\mathrm{A}$): The flow of solvent molecules from a pure solvent to the solution through semipermeable membrane is osmosis.

Reason $\left(\mathrm{R}\right):$ Pure solvent molecules flow out of the solution through semipermeable membrane if a pressure larger than the osmotic pressure is applied to the solution side.

The correct answer is:
