When the products are in equilibrium under the reaction conditions, the relative amounts of products depend on their stabilities, and the reaction is under thermodynamic control. During the reaction, the reaction may follow a kinetic pathway where the reaction proceeds through a high-energy intermediate to form the kinetic product. Alternatively, the reaction may follow a thermodynamic pathway where the reaction proceeds through a lower energy intermediate to form the more stable thermodynamic product. At equilibrium, the thermodynamic product is typically favored over the kinetic product. Therefore, choice D is the correct statement.
