The best answer is C. they both produce chemical and electrical energy.
ATP (adenosine triphosphate) is a molecule that stores and provides energy for various cellular processes in living organisms. Photovoltaic cells convert light energy directly into electrical energy. Both systems are fundamental in their respective contexts for energy conversion: ATP in biological systems and photovoltaic cells in renewable energy technology.
The other options are not accurate in the context of the similarities between ATP and photovoltaic cells.
