Answer: Option (C) is the correct answer.
Step-by-step explanation:
In a chemical reaction equation, the number of species or molecules written on the left hand side denote reactants whereas the species or molecules written on the right hand side denote products.
For example, in the given equation,
. Left hand side molecule is
and it is the reactant. Whereas the molecules or species on right hand side are S and
and these are the products.
Thus, we can conclude that the product(s) in this equation would be S + O2.
