B) color charge.
C) electric charge.
D) lepton number.
E) spin.

Question

Quizplus · Accepted Answer

This is because of the Pauli exclusion principle, which states that no two identical fermions (particles with half-integer spin) can occupy the same quantum state simultaneously. Since quarks are fermions, three quarks in a baryon must have different color charges (red, green, blue or anti-red, anti-green, anti-blue).
