Elements in the reactants: C , H, O

Elements in the products : C, H, O

A. nitrogen, sulfur, and sodium only This option is incorrect neither sulfur not sodium are in the reactants.

B. carbon and hydrogen only This option is wrong, Oxygen is lacking

C. carbon, hydrogen, and oxygen only  This is the right option carbon, hydrogen and oxygen are the same elements in the reactants and in the products,
