What energy transformation occurs in photosynthesis?

Photosynthesis takes light energy from the sun and stores it as chemical energy in glucose. Chlorophyll captures light and drives reactions that first produce energy carriers (ATP and NADPH) and then use them to assemble carbon dioxide and water into glucose. The important point is that the energy ends up stored in the chemical bonds of glucose, not as light or heat. So of the options, the correct one describes light energy being converted into chemical energy stored in glucose. The other ideas don’t match what happens in photosynthesis: it isn’t turning electrical energy into light, nor heat into chemical energy, and it doesn’t convert chemical energy into light energy.
