Answer:
A. The boiling and condensation points of a substance are the same
Explanation:
The boiling point of a substance is the temperature at which it changes from liquid to gas while the point at which a substance changes from gas to liquid is called its condensation point. As long as a substance is pure, it condenses at the same point at which it boils.
Pure water for example has a condensation point and boiling point of 100 degrees Celsius.
