- A. J.J Thomson
- B. Chadwick
- C. Rutherford
- D. Neil Bohr
Explanation
Sir James Chadwick is the correct answer. He discovered the neutron in 1932, which is a subatomic particle with no charge. This discovery was instrumental in understanding the structure of atomic nuclei and earned Chadwick the Nobel Prize in Physics in 1935.

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.
