In beta-plus decay (β+ decay), a proton in the nucleus is converted into a neutron, and a positron (the antimatter counterpart of an electron) is emitted. As a result, the mass number remains the same, and the atomic number decreases by one.
Therefore, the correct response is:
The mass number remains the same, and the atomic number decreases by one.
