c.
the elements cannot be determined
d.
carbon and hydrogen only
correct answer is b i answered my own question! lol

The correct answer is Option B.

Explanation:

Every balanced chemical equation follows law of conservation of mass. This law states that mass can neither be created nor be destroyed but it ca only be transformed from one form to another form.

In a chemical reaction, total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side.

During a chemical reaction, the atoms on the reactant side must also be present on the product side.

For the given reactants, the chemical equation will follows:

As, the reactant side contained carbon, hydrogen and oxygen atoms only. So, the product will also contain the same atoms.

Hence, the correct answer is Option B.
