If the products of a chemical reaction contain less potential energy than
the reactants,

A. energy has been stored in the molecular bonds of the product.
B. the reaction will be reversible without additional energy input.
C. no energy exchange occurred.
D. a synthesis reaction is likely to have occurred.
E. energy has been released by the breaking of molecular bonds.

Please explain, Thank you

The energy has been released by the breaking of molecular bonds if the products contain less energy than the reactants and it's a kind of exothermic reaction.

There will be lesser enthalpy throughout the product more often than in the reaction mixture and therefore a minus or low enthalpy has been said to occur in such a process called Exothermic.
In the other words, this same energy intended to breakdown down the bonds between the molecules would be less than whenever the product lines create the new ones.

Thus Option E is the appropriate alternative.
