Suppose a claim is made that the decay of the neutron is given by n \rightarrow p+e^{-} . What conservation laws are violated by this decay? (a) energy (b) angular momentum (c) electric charge (d) baryon number (e) electron-lepton number (f) muon-lepton number (g) tau-lepton number (h) no conservation laws

(b), (e). There is one spin- \frac{1}{2} particle on the left and two on the right, so angular momentum is not conserved. There are no leptons on the left and an electron on the right, so electron lepton number is not conserved.
