Question

What is not true about the following particles: muon, pion, kaon?

• A. Rest mass of muon is less than that of pion or kaon
• B. All are mesons
• C. Muon is a lepton while pion and kaon are mesons
• D. All of them have corresponding anti-particles

Answer 1

The correct option is B All are mesons

Mesons examples are $PION$, $KAON$ & $PSI$ while $MUON$ is a lepton having charge of $-1$ (electron charge).
