The correct answer is B. Equilibrium is achieved. When the forward and reverse paths of a change
occur at the same rate, the system is in equilibrium specifically in dynamic equilibrium. Dynamic equilibrium is the balance in a process
that is continuing. It is achieved in a reaction when the forward rate of
reaction and the backward rate of reaction is at the same value or equal.

Answer:

b. equilibrium.

Explanation:

When a chemical reaction and its reverse occur at the same time and at the same speed, the reaction reaches equilibrium. This is because both reactions end up nullifying their "influence" generating dynamic equilibrium, where all forms acting on the reaction are nullified. Thus there is no reaction sticking out in the system, so we can state that the reaction is in equilibrium.
