Binary eutectic phase diagram describes chemical behavior of two immiscible components from completely mixable components. On abscissa( x - axis) we plot composition of components and ordinate (y-axis) variation of temperature. The line R is liquidus which separate all melt components to melt + crystal components (chemical). The line P is eutectic temperature. And Q line is eutectic composition of components.
so the correct answer is
R line- liquidus
P line - eutectic temperature
Q line - eutectic composition
