(A) When a positron is emitted, a proton is converted into a neutron, a positron, and a neutrino as shown in the reaction: $^1_1H \rightarrow ^1_0n + ^0_{+1}e + \nu$.Since a proton is converted into a neutron, the total number of nucleons (mass number) remains constant, but the number of protons (atomic number) decreases by $1$ unit.
