What type of energy does the Sun produce?

  1. Nuclear

  2. Chemical

  3. Mechanical

  4. Solar

The correct answer is: Nuclear

The sun produces nuclear energy through a process called nuclear fusion. This involves the fusion of hydrogen atoms to form helium, resulting in the release of large amounts of energy in the form of heat and light. Options B and C (Chemical and Mechanical) are incorrect because they do not accurately describe the type of energy produced by the Sun. Option D (Solar) is also incorrect because solar energy is the energy that is received from the Sun, not the type of energy that it produces. Therefore, the only correct choice is option A (Nuclear).
