Multiple choice

According to the spin-statistics theorem, what determines whether a fundamental particle is a boson or a fermion?

Its electric charge: neutral particles are bosons and charged particles are fermions
Its mass: light particles are bosons and heavy particles are fermions
Its speed: particles moving at the speed of light are fermions and slower ones are bosons
Its spin: integer spin (0, 1, 2, ...) particles are bosons; half-integer spin (1/2, 3/2, ...) particles are fermions
