You have been given an assertion statement and a reason. Select from A- D to locate the correct statement ? A) Both assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the assertion (A). B) Both Assertion (A) and reason (R) are true but Reason (R) is the not the correct explanation of the assertion (A). C) Assertion (A) is true, but Reason (R) is false. D) Assertion (A) is false, but Reason (R) is true. Assertion (A): At the triple point, the vapor pressure of the substance is equal for all three phases.Reason (R): The Clausius-Clapeyron equation can be used to describe pressure changes along all phase boundaries.
