The correct answer is:
If both assertion and reason are false.
Elevation in boiling point $\left(\Delta T_b\right)=K_b \times m$ Depression in freezing point $\left(\Delta T_f\right)=K_f \times m$. Elevation in boiling point and depression in freezing point are colligative properties i.e., they depend only on the number of particles of the solute. Value of $K_b$ and $K_f$ are different, so $\Delta T_b$ and $\Delta T_f$ are also different.
