In a complex reaction where an intermediate is incorporated, the rate of the reaction depends on multiple factors. The formation and consumption of the intermediate during the reaction affect the overall rate of the reaction.

Option 4 is correct. The rate of the reaction depends on the concentration of reactants, products, and the intermediate. The concentration of reactants affects the rate of the forward reaction, the concentration of products affects the rate of the backward reaction, and the concentration of the intermediate affects both the forward and backward reactions. If the concentration of any of these species is changed, it will affect the rate of the overall reaction.

Option 1, 2, and 3 are false. The rate of the reaction is not solely dependent on the concentration of reactants, products, or intermediate. All three factors play a role in determining the rate of the complex reaction.

It is important to note that the concentration of the intermediate is not constant throughout the reaction as it is formed and consumed. Hence, the concentration of the intermediate should also be considered while determining the rate of the reaction in complex reactions where an intermediate is incorporated.
