Particles which are not composite and hence truly elementary are

Options

  1. Amesons
  2. Bprotons
  3. Cneutrons
  4. Dleptons

Correct answer

D. leptons

Step-by-step solution

Of these leptons are truly elementary particles. While rest are composed of quarks, so they are composite particles.
