(D) As vapours are removed,the remaining solution becomes more concentrated. The freezing point depression is defined as $\Delta T_f = K_f \times m$. As the molality $m$ increases,$\Delta T_f$ increases,which means the freezing point $(T_f = T_f^0 - \Delta T_f)$ decreases. Osmotic pressure is given by $\Pi = CRT$. As the concentration $C$ increases,the osmotic pressure $\Pi$ increases. Therefore,the freezing point decreases and the osmotic pressure increases.
