A radioactive nucleus $\displaystyle { }_{\mathrm{Z}}^{\mathrm{A}} \mathrm{X}$ undergoes spontaneous decay in the sequence
$\displaystyle { }_{\mathrm{Z}}^{\mathrm{A}} \mathrm{X} \rightarrow \mathrm{Z}-1 \mathrm{~B} \rightarrow \mathrm{Z}-3 \mathrm{C} \rightarrow \mathrm{Z}-2 \mathrm{D}$, where Z is the atomic number of element X. The possible decay particles in the sequence are :
