NaCl is an electrolyte which on dissociation give two ions. Whereas urea is not an electrolyte. Hence, osmotic pressure of 0.1 M NaCl is almost double than that of 0.1 M urea solution.

Q. Assertion $(A)$ Osmotic pressure $0.1 N$ urea solution is less than that of $0.1 M$ $N a Cl$ solution
Reason $(R)$ Osmotic pressure is not a colligative property.
