Answer:

Exothermic reaction  

Explanation:

Consider the reaction

A + B ⟶ C

If energy is released, the product C is at a lower potential energy level than the reactants A and B (see diagram).

Conversely, the reactants A and B are at a higher energy level than the product.

B is wrong. In an endothermic reaction, the reactants A and B are at a lower energy level than the product.

C and D are both wrong. Both types of reaction can be exo- or endothermic.
