(A) In $\beta$-decay,the energy released is shared between the $\beta$-particle and an antineutrino (or neutrino). Since the energy is shared,the $\beta$-particle can have any energy ranging from $0$ to a maximum value $E_{max}$ (often denoted as $E_0$). The distribution of the number of $\beta$-particles $N(E)$ versus energy $E$ is a continuous spectrum that starts from $0$,reaches a peak,and then drops to $0$ at $E = E_0$. This characteristic shape is represented by the graph shown in option $A$.

The energy spectrum of $\beta$-particles [number $N(E)$ as a function of $\beta$-energy $E$] emitted from a radioactive source is:
