(B) The reaction is $2 A \rightleftharpoons B + C$. The reaction quotient $Q$ is given by the expression: $Q = \frac{[B][C]}{[A]^2}$. Substituting the given concentrations: $Q = \frac{(6 \times 10^{-5}) \times (6 \times 10^{-5})}{(6 \times 10^{-5})^2} = 1$. Since $Q = 1$ and $K_{eq} = 2 \times 10^{-3}$,we observe that $Q > K_{eq}$. When $Q > K_{eq}$,the reaction proceeds in the backward direction to reach equilibrium.
