Solution

The correct option is D Assertion is incorrect but Reason is correct
$0.1 M K C l, 0.1 M K_{2} {S O}_{4}$ solutions cause different osmotic pressure in solution as the Vant Hoff's factor for KCl and $K_{2} {S O}_{4}$ are 2 and 3 respectively.
Osmotic pressure is a colligative property and depends on the number of particles present in the solution.
Assertion is incorrect but Reason is correct.
Note: osmotic pressure, $Π = i C R T$
