The sun converts nuclear energy into light and heat through a process called nuclear fusion. This is a process of combining atomic nuclei to create a heavier nucleus, which releases a large amount of energy. Option B, kinetic energy, is the energy of motion and is not involved in the production of sunlight. Option C, potential energy, is the energy stored in an object's position or state, but it is not the primary source of energy for the sun. Option D, heat energy, is a form of energy that is lost during the nuclear fusion process, rather than being converted into it. Therefore, the correct option is A, nuclear energy.
