Solution

The correct option is C $P_{2} > P_{1} > P_{3}$
The osmotic pressure is inversely proportional to the molecular weight.
The increasing order of molecular weights is $urea < glucose < sucrose$ .
Hence, the decreasing order of osmotic pressure is $P_{2} > P_{1} > P_{3}$ .
Hence, the correct option is $C$
