Carbon-14 undergoes decay to nitrogen-14 by releasing a $\beta^-$ particle. Which statement describes why the emitted $\beta^-$ particles have a spread of different kinetic energies?
- AThe carbon-14 nuclei have slightly different masses.
- BThe emitted $\beta^-$ particles have a range of different masses.
- CThe energy released in the decay process is different for each carbon-14 nucleus that decays.
- DThe energy released in the decay process is shared between the nitrogen-14 nucleus, a $\beta^-$ particle and an antineutrino.
