Ethen Kramer · Answer 1

The reaction of radiodecay of carbon C-14 is

C-14 - - > N-14 + e - + (ve)

where e - is an electron and (ve) is an electron-type antineutrino.

Basically, when the carbon nucleus (atomic number: 6, mass number: 14) decays, a neutron of the nucleus converts into a proton (therefore, the mass number remains the same, 14, but the atomic number increases by 1, therefore it becomes nitrogen) and releases an electron-antineutrino pair.

So, the correct answer is C), N-14.
