During the process of beta (β-) emission, a neutron in the nucleus of an atom is converted into a proton, an electron, an electron antineutrino, and energy. Based on conservation laws, how does the mass of the neutron compare to the mass of the proton?

• Mass of neutron > Mass of proton

• Mass of neutron < Mass of proton

• Mass of neutron = Mass of proton

• Cannot be determined
