Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
0.02m solutions of urea and sucrose will freeze at the same temperature because the depression in the freezing point of a solution is directly proportional to the concentration of the solution and van't Hoff factor is same for both i.e. 1.

The freezing point of a solution is inversely proportional to the concentration of the solution.
Hence, option $B$ is correct.
