The example of nuclear fusion is
Correct answer: B. formation of helium from hydrogen
- A. formation of barium and krypton from uranium
- B. formation of helium from hydrogen
- C. formation of plutonium-235 from uranium-235
- D. formation of water from hydrogen and oxygen
Explanation
B is the right option because Nuclear fusion involves the combining of lighter atomic nuclei to form a heavier nucleus. In the example given, the fusion of hydrogen nuclei (protons) to form helium nuclei is a representation of nuclear fusion.

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.
