A liquid alloy of the eutectic composition (L) undergoes the eutectic reaction to give α and β phases of compositions a and b respectively. The ratio of the relative amounts of α and β phases is
A. $$\frac{{\left( {b - L} \right)}}{{\left( {L - a} \right)}}$$
B. $$\frac{{\left( {L - a} \right)}}{{\left( {b - L} \right)}}$$
C. $$\frac{{\left( {b - LI} \right)}}{{\left( {b - a} \right)}}$$
D. $$\frac{{\left( {L - a} \right)}}{{\left( {b - a} \right)}}$$
