We know that nucleons are fermion and photon is a boson. Fermions obey the Pauli exclusion principle but bosons do not obey the rule. According to this rule a fermion do not share quantum state i. e, any two identical fermion can not occupy in the same quantum state but for bosons there is no restriction. So we can say that B bag contains more number of particles than A.
