What is conserved during a chemical reaction matter, energy, both, or niether?

Option (c) is the correct answer.

Explanation:

According to the law of conservation of energy or matter, it is stated that energy can neither be created nor it can be destroyed. It can only be transformed from one form to another.

Same applies to the matter that matter can be transformed from one form to another.  

Thus, we can conclude that during a chemical reaction both matter and energy is conserved.
