Correct answer: B. Positron
- A. Proton
- B. Positron
- C. Electron
- D. Photon
- E. Gamma ray
Explanation
n the equation for nuclear decay p^1 →n^1 + x , the particle x represents a positively charged particle, typically a positron (e+) or beta plus particle (β+).

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.
