The fact that most $\alpha$ emitters show a group of discrete $\alpha$-particle energies,rather than a single energy,can best be explained by which of the following?
A)$\alpha$ particles and $\beta$ particles are emitted from the same unstable nucleus,and because the $\beta$ particles exhibit discrete energies,so must the $\alpha$ particles.
B)The parent can decay by $\alpha$ emission to any one of a number of allowed energy states of the daughter.
C)An $\alpha$-emitting parent normally decays to many different daughter elements.
D)$\alpha$ emission is accompanied by neutrino emission.
E)Varying amounts of energy are required to tunnel through the nuclear potential well.
