A raclioactive nucleus \({ }_{Z}^{A} X\) undergoes spontaneous decay in the sequence \({ }_{Z}^{A} X \rightarrow_{z-1} B \rightarrow_{Z-3} C \rightarrow_{Z-2} D\), where \(Z\) is the atomic number of element \(X\). The possible decay particles in the sequence are :
A. \(\alpha, \beta^{-}, \beta^{+}\)
B \(\alpha, \beta^{+}, \beta^{-}\)
(c) \(\beta^{+}, \alpha, \beta^{-}\)
D \(\beta^{-}, \alpha, \beta^{+}\)
