The correct answer is b) an exothermic reaction. An exothermic reaction is a chemical reaction where energy is released into the surroundings. The easiest way to determine the answer to this question is to understand the definitions of endothermic and exothermic reactions.

An endothermic reaction, on the other hand, is a chemical reaction that absorbs energy from the surroundings. This means that the reaction requires an input of energy in order to occur.

To answer this question on your own, you can remember that "exo" means "out" or "release," while "endo" means "into" or "absorb." So, in the case of an exothermic reaction, energy is released, which is the definition given in option b).
