The correct answer is: $\beta, \alpha, \gamma$
$$
\begin{aligned}
& \mathrm{Z}^{\mathrm{X}^{\mathrm{A}} \stackrel{\beta}{\longrightarrow}} \mathrm{Z+1} \mathrm{Y}^{\mathrm{A}} \stackrel{\alpha}{\longrightarrow} \mathrm{Z}_{-1} \mathrm{~B}^{\mathrm{A}-4} \stackrel{\gamma}{\longrightarrow} \\
& \mathrm{Z}-1 \mathrm{~B}^{\mathrm{A}-4} \\
&
\end{aligned}
