A. The products will have more energy than the reactants
B. Energy will not be required for the reaction to happen at room temperature
C. The products will have less energy than the reactants
D. Energy will be required for the reaction to happen at room temperature

The statement that is always true for exothermic reactions is:

C. The products will have less energy than the reactants.

In exothermic reactions, energy is released to the surroundings, which typically means that the products have a lower energy state than the reactants.
