Answer: Option (b) is the correct answer.

Explanation:

Since energy of reactants is less than the energy of products. Therefore, it means energy is absorbed during the reaction.

As the energy required to break the bonds in the reactants is greater than the energy released when products are formed.  

Therefore, it is an endothermic reaction.

Thus, we can conclude that the statement, it is endothermic because the energy required to break bonds in the reactants is greater than the energy released when the products are formed is correct.
