A. Positron
B. Neutron✓ Correct Answer
C. Proton
D. Neutrino

💡 Solution & Explanation

James Chadwick discovered the neutron in 1932 by bombarding beryllium with alpha particles, establishing the existence of a neutral subatomic particle possessing nearly the same mass as a proton. Other particles like positrons and neutrinos were discovered through different experimental particle physics investigations. Fundamental scientific discoveries form regular components of general science questions.
