During β⁻ decay, which change takes place to the quark composition of the nucleus that emits the β⁻ particle, and which other particle is emitted? [Table with columns: quark change, other particle emitted. Rows for A, B, C, D show different changes and particles.]
Aquark change: down to up, other particle emitted: antineutrino
Bquark change: down to up, other particle emitted: neutrino
Cquark change: up to down, other particle emitted: antineutrino
Dquark change: up to down, other particle emitted: neutrino
