BR gen chem, Section 8, passage XI, question 74

Had Metal III been used in Experiment II instead of Metal IV, the final temperatures for the liquids would have been:

I answered C (the answer is D) because both Metal III and Metal IV are heated up to the same temperature before being placed in the liquid. They are heated to the SAME temperature, which would indicate they have the same energy. In the liquid, the metal with the high heat capacity (metal IV) would give off less heat, while retaining most of it, while the metal with the smaller heat capacity would give off a greater amount of heat, while retaining a smaller amount of heat. Thus the temp for liquid with Metal IV would be lower, and, for liquid with Metal III would be higher.

What do you guys say?
