Solar energy is mainly caused due to (a) burning of hydrogen in the oxygen (b) fission of uranium present in the Sun (c) fusion of protons during synthesis of heavier elements (d) gravitational contraction

Answer: (c). In the Sun's core, hydrogen nuclei (protons) fuse to form helium, releasing energy from the mass defect. It is not chemical burning, not fission, and gravitational contraction is not the main source now. So the answer is (c).
