Correct Answer: PositronYour Answer: A
Last Updated:
The correct answer is Option A — Positron. A positron is the antiparticle of an electron. It has the same mass as an electron but opposite charge (+1.6 × 10⁻¹⁹ C). It was discovered by Carl Anderson in 1932.
Why other options are wrong:
Option B (Neutrino): A neutrino is a neutral, almost massless particle associated with weak interactions. It is NOT the antiparticle of electron.
Option C (Antineutrino): An antineutrino is the antiparticle of neutrino, not of electron.
Option D (Muon): A muon is a heavier version of electron but is NOT its antiparticle.
