Correct: "The energy of the products is lower than that of the reactants."
Explanation: Exothermic reactions release energy to the surroundings, so the products end up at a lower energy (enthalpy) than the reactants (ΔH < 0). The statements about complexity are not generally true — complexity of molecules does not determine whether a reaction is exothermic. The third statement is the opposite of the correct one.
