Answer 1

The answer A.The product of a combustion reaction

Step-by-step explanation:

A catalyst is the substance which helps in increasing the rate of a reaction without itself getting consumed in the reaction.

A catalyst changes the path of reaction so that molecules with lower energy can easily participate in the reaction. As a result, formation of products increases.

Thus, we can conclude that out of the given options, a catalyst is not used up in a reaction.
