The answer is the option (2) The concentrations of the products and the reactants are constant. That is a result of a dynamic equilibrium. The dynamic equilibrium is reached when the rates of forward reaction and the reverse reaction are equals, which yields to a zero net change in the concentrations of products and reactants.
