A single neutron decays into a proton, a $\beta^{-}$ particle and an antineutrino. Which row shows the quark structure of the neutron and of the proton, together with the force responsible for this reaction?
- Aneutron: down, down, up; proton: down, up, up; strong interaction
- Bneutron: down, down, up; proton: down, up, up; weak interaction
- Cneutron: down, up, up; proton: down, down, up; strong interaction
- Dneutron: down, up, up; proton: down, down, up; weak interaction
