Q. In the hypothetical isobaric ternary liquidus projection diagram given below, solid phases A, B, C, D and E exist in equilibrium with liquid. The reaction taking place at the isobaric invariant point W is
A. Liquid (at W) = B + D + E
B. Liquid (at W) = A + B + D
C. Liquid (at W) + E = B + D
D. Liquid (at W) + B + D = E
Ans: Liquid (at W) + B + D = E
