If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

(A) According to the Clausius-Clapeyron equation,the slope of the melting curve is given by $\frac{dP}{dT} = \frac{L}{T(V_2 - V_1)}$,where $L$ is the latent heat of fusion,$T$ is the temperature,$V_2$ is the volume of the liquid phase,and $V_1$ is the volume of the solid phase. For water,ice contracts upon melting,meaning the volume of water $(V_2)$ is less than the volume of ice $(V_1)$. Therefore,$(V_2 - V_1) Thus,both the Assertion and the Reason are correct,and the Reason is the correct explanation for the Assertion.
