Explanation:
In beta-plus decay (also known as positron emission), a nucleus emits a positron (a positively charged electron) and a neutrino. This process results in the conversion of a proton in the nucleus into a neutron. As a result, the atomic number (which represents the number of protons) decreases by one, while the mass number (which represents the total number of protons and neutrons) remains the same. So, the correct option is "The mass number remains the same, and the atomic number decreases by one."
