Answer

Brief Explanations:

When a closed - jar filled with water is kept at a constant temperature, a dynamic equilibrium is established at the water surface. Water molecules continuously evaporate from the surface and also condense back into the liquid state. At equilibrium, the rate of evaporation equals the rate of condensation.

Answer:

A. Water molecules evaporate and condense at the same rate.
