Quizplus · Accepted Answer

In any reaction, if the total number of baryons, total electric charge, and the total lepton number before and after the reaction remains the same, the reaction is said to be conserved with respect to these quantities. This is known as the conservation of baryon number, charge, and lepton number, respectively. Therefore, in the given reaction, all of these quantities are conserved.
