Assertion (A): `0.1 M` solution of glucose has same increment in freezing point than has `0.1 M` solution of urea.
Reason (R ): `K_(f)` for both has different value.

Options

A. If both assertion and reason are true, and reason is the true explanation of the assertion.
B. If both assertion and reason are true, but reason is not the true explanation of the assertion.
C. If assertion is true, but reason is false.
D. If both assertion and reason are false.

Explanation

Correct A. Both being non-electrolytes with same molar concentration will have same decrease (not increment) in freezing point.
Correct R. Both being aqueous solution, i.e., solvent is same (water), `K_(f)` will be same for both.
