Gibbs free energy

Chemistry Level 2

Assume that, at a constant temperature of 2 5 ∘ C 25 ^\circ \text{C} , gas A \ce{A} was injected into a container and gas B \ce{B} was produced from gas A \ce{A} . At t t seconds later, a chemical equilibrium was reached as follows: A ( g ) ⇌ B ( g ) . \ce{A}(g) \rightleftharpoons \ce{B}(g).

Which of following is not correct about this equilibrium state?

If more forward reaction proceeds, then Gibbs free energy of the system decreases. Gibbs free energy of the system becomes minimized at the equilibrium. Gibbs free energy of pure A is larger than that of the equilibrium. Gibbs free energy of pure B is larger than that of the equilibrium.

This question is easy. But I suggest something to the problem writer: 3 of the options mean the same, while the fourth is the odd one out, so it's easy to guess the answer.
