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.
