Pion is an abbreviation of pi meson.

Mesons always comprise one quark and one anti-quark.

c) and d) are excluded because there are three quarks. b) is excluded because it only has two quarks neither of which is anti.

a) is the correct answer.

Thanks!!! So basically are all "ons" short for mesons?

If only particle physics were that simple! Sadly, no.

You only need to look at say protons or neutrons comprising three quarks for that simple nomenclature to be thwarted.
