The main source of solar energy is
Correct answer: C. nuclear fusion
- A. nuclear fission
- B. gravitational contraction
- C. nuclear fusion
- D. combustion
Explanation
C is the right option because The main source of solar energy is nuclear fusion. In the core of the Sun, hydrogen nuclei combine under immense pressure and temperature to form helium nuclei, releasing a vast amount of energy in the process. This process, known as nuclear fusion, powers the Sun and provides the energy that sustains life on Earth.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
