The heat released for a certain mass of water that is condensing is calculated by multiplying the heat of vaporization and the amount of the substance. Calculation is as follows:
Heat released = (40.7 kJ/mol) (27.9 g) ( 1 mol / 18 g) = 63.09 kJ
Therefore, the correct answer from the choices listed above is option C.
