A student injects equal volumes of two pure liquids, X and Y, into separate evacuated rigid containers of equal volume maintained at 25 °C. After dynamic equilibrium is established, excess liquid remains at the bottom of both containers, and the measured vapor pressure in the container with liquid X is significantly higher than that in the container with liquid Y. Based on these experimental observations, which statement correctly compares the properties of the two liquids?

A) Liquid X has stronger intermolecular attractive forces than liquid Y, allowing its molecules to escape into the vapor phase more readily.

B) Liquid Y has stronger intermolecular attractive forces and a higher normal boiling point than liquid X.

C) Liquid X exhibits a lower initial rate of evaporation and a higher molar heat of vaporization than liquid Y.

D) Doubling the volume of liquid remaining in the container of liquid Y would double its measured equilibrium vapor pressure.
