(C) The concentrations of the species are: $[A] = \frac{2 \ mol}{100 \ L} = 0.02 \ M$,$[B] = \frac{0.25 \ mol}{100 \ L} = 0.0025 \ M$,and $[C] = \frac{0.5 \ mol}{100 \ L} = 0.005 \ M$. The reaction quotient $Q_c$ is calculated as: $Q_c = \frac{[C]^2}{[A]^2[B]} = \frac{(0.005)^2}{(0.02)^2 \times 0.0025} = \frac{0.000025}{0.0004 \times 0.0025} = \frac{0.000025}{0.000001} = 25$. Since $Q_c = K_c = 25$,the reaction is in a state of equilibrium.
