The solid-liquid phase diagram for the Mg-Zn system is shown in the figure below where the vertical line at $\mathrm{X}(\mathrm{Mg})=0.33$ represents the formation of a congruent melting compound $\mathrm{MgZn}_{2}$. The figure is divided into seven regions depending upon the physical state of the system. The composition of the region \#6 represents.
(a)Single phase of a solution of Mg and Zn
(b)Two phase region between the solid Zn and solid $\mathrm{MgZn}_{2}$
(c)Two phase region between the liquid and solid $\mathrm{MgZn}_{2}$
(d)Two phase region between solid Mg and solid $\mathrm{MgZn}_{2}$
