Answer

Galvanic cells and fuel cells work on different principles. A galvanic cell converts chemical energy into electrical energy through spontaneous redox reactions. In contrast, fuel cells involve a controlled reaction with fuel, typically producing electricity and water. While both types of cells produce electricity, they do so via different mechanisms, thus leading to the conclusion that they have different energy transformations. Therefore, option C is the correct choice.
