Mark all the leptons a) Proton b) Electron c) Anti-top d) Gluon e) Tau Neutrino

Electron, Tan Neutrino,

Explanation:

A lepton is an elementary particle of half-integer spin (spin 1⁄2) that does not undergo strong interactions. Two main classes of leptons exist, charged leptons (also known as the electron-like leptons), and neutral leptons (better known as neutrinos).
