The following solutions were prepared by dissolving 10 g of glucose \( (\text{C}_6\text{H}_{12}\text{O}_6) \) in 250 mL of water \( (\text{P}_1) \), 10 g of urea \( (\text{CH}_4\text{N}_2\text{O}) \) in 250 mL of water \( (\text{P}_2) \) and 10 g of sucrose \( (\text{C}_{12}\text{H}_{22}\text{O}_{11}) \) in 250 ml of water \( (\text{P}_3) \). The right option for the decreasing order of osmotic pressure of these solutions is _______.

1. A
   \( \text{P}_1 > \text{P}_2 > \text{P}_3 \)
2. B
   \( \text{P}_2 > \text{P}_3 > \text{P}_1 \)
3. C
   \( \text{P}_3 > \text{P}_1 > \text{P}_2 \)
4. D
   \( \text{P}_2 > \text{P}_1 > \text{P}_3 \)
