Answer:

Option B is correct.

B. In an exothermic reaction, excess energy is released as heat.

Explanation:

An exothermic reaction is a chemical reaction that releases energy by light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants → products + energy. Exothermic Reaction means "exo" meaning releases and "thermic" means heat.
