A sample of pure \(\text{XY(g)}\) containing \(8\) molecules is introduced into an evacuated, rigid container at a constant temperature. The reversible decomposition reaction reaches dynamic chemical equilibrium according to the equation below.

\[ 2\,\text{XY(g)} \rightleftharpoons \text{X}_2\text{(g)} + \text{Y}_2\text{(g)} \qquad K_c \ll 1 \]

Which of the following particulate diagrams best represents the contents of the container at equilibrium?
