Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Assertion
Meniscus of a liquid disappears at the critical temperature. Thus, there is no separation between liquid phase and gas phase.
Reason
Density of liquid and its gaseous phase become equal at the critical temperature. In other words, the difference in the densities between gas phase and liquid phase is zero.
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
