2021 1 question

1. 1 Solutions Medium
   The following solutions were prepared by dissolving 10 g of glucose ($C_6H_{12}O_6$) in 250 ml of water ($P_1$), 10 g of urea ($CH_4N_2O$) in 250 ml of water ($P_2$) and 10 g of sucrose ($C_{12}H_{22}O_{11}$) in 250 ml of water ($P_3$). The right option for the decreasing order of osmotic pressure of these solutions is:
   A $P_1>P_2>P_3$ B $P_2>P_3>P_1$ C $P_3>P_1>P_2$ D $P_2>P_1>P_3$
