If both the Assertion and Reason are incorrect.

(D) The melting point of ice decreases with an increase in pressure. Since atmospheric pressure decreases at high altitudes,the melting point of ice actually increases,meaning it does not melt faster.Therefore,the assertion is false.Additionally,atmospheric pressure is lower,not higher,at high altitudes,making the reason also false.Thus,both the assertion and the reason are incorrect.
