During endothermic reaction, thermal energy is absorb by the system from the surrounding. The correct option is C.

Answer: Option (c) is the correct answer.

Explanation:

When energy is absorbed by a system or reactants then the reaction is known as endothermic in nature. In this type of reaction, energy of reactants is less than the energy of energy of products.

Whereas when energy is released by a system or reactant then then the reaction is known as exothermic in nature. In this type of reaction, energy of reactants is more than the energy of products.

Thus, we can conclude that the statement thermal energy is absorbed by the system, best describes an endothermic reaction.
