In the hypothetical isobaric ternary liquidus projection diagram given below, solid phases

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
