Answer:

C

Explanation:

the enthalpy of reaction is independent of the reaction path

The statement with related to the Hess's law should be the enthalpy of reaction that does not based on the reactions.

What is Hess's law?

It is also called as the  Hess's law of constant that should be heat summation. In the year 1840 here the heat should be absorbed or it should be evolved or there should be changed in the enthalpy with respect to the chemical reaction that contain the fixed quantity.

Therefore, we can conclude that the option c is correct.
