correct answer is c, converts light energy into chemical energy

The correct answer is It converts light energy to chemical energy. That is because creation of oxygen is not done for us, the plants don't really care. The oxygen created is a side addition to the fact that plants create energy for themselves. They take light energy and convert it into energy for themselves made out of chemicals, oxygen being their waste that we use.
