What is the correct increasing order of reactivity of the metals X, Y and Z based on the following information?

$$\begin{array}{*{20}{l}} {{\text{XC}}{{\text{l}}_2} + {\text{Y}} \to {\text{YC}}{{\text{l}}_2}{\text{X}}} \\ {{\text{ZC}}{{\text{l}}_2} + {\text{X}} \to {\text{XC}}{{\text{l}}_2}{\text{Z}}} \\ {{\text{YC}}{{\text{l}}_2} + {\text{Z}} \to {\text{no reaction}}} \end{array}$$

A.     ${\text{Z}} < {\text{X}} < {\text{Y}}$

B.     ${\text{Y}} < {\text{X}} < {\text{Z}}$

C.     ${\text{Z}} < {\text{Y}} < {\text{X}}$

D.     ${\text{X}} < {\text{Z}} < {\text{Y}}$
