4. Consider the isothermal section of an XYZ ternary phase diagram (mol %) shown below.(a) Label the diagram with appropriate Greek letters in each region to indicate which represent singlephases, two phases, three phases, etc. [5 points](b) Give the composition at points 1 and 2 and draw plausible tie lines in each region of the diagramfor which tie lines are appropriate. [5 points](c) Consistent with your work above, indicate the composition of each phase present and the fractionof each phase
