What are \(X, Y\) and \(Z\) in the following reactions?
\[
\begin{aligned}
& \mathrm{CaCO}_3 \stackrel{\Delta}{\rightleftharpoons} \mathrm{CO}_2+X \\
& X+\mathrm{H}_2 \mathrm{O} \longrightarrow Y \\
& Y+\mathrm{Cl}_2 \longrightarrow Z \\
& X \quad Y \quad Z
\end{aligned}
\]
- A \(\begin{array}{lll}\mathrm{CaO} & \mathrm{Ca}(\mathrm{OH})_2 & \mathrm{CaOCl}_2 \cdot \mathrm{H}_2 \mathrm{O}\end{array}\)
- B \(\begin{array}{lll}\mathrm{CaO} & \mathrm{Ca}(\mathrm{OCl})_2 & \mathrm{Ca}(\mathrm{OH})_2\end{array}\)
- C \(\mathrm{Ca}(\mathrm{OCl})_2 \quad \mathrm{Ca}(\mathrm{OH})_2 \quad \mathrm{CaO}\)
- D \(\mathrm{Ca}(\mathrm{OH})_2 \quad \mathrm{CaO} \quad \mathrm{Ca}(\mathrm{OCl})_2\)
