Good Work, Kids

Which of these subatomic particles has a fractional charge?
a) neutrino
b) photon
c) quark <---- THE ANSWER!!!
d) positron

A neutrino has no charge, a photon has no charge (WTF is a photon? Every time I think about this, it blows my mind), and a positron has a +1 charge.

But a quark has a either a -1/3 charge (down-type) or a +2/3 charge (up-type).

HOWEVER, there's no such thing as a quark by itself. They're always stuck together in the form of hadrons. A quark is an elementary particle and a hadron is a composite particle. Protons and neutrons are hadrons.

All of that is pretty much useless information. I don't know any practical information that might be beneficial some day. I apologize most sincerely.
