Solution

The correct option is C decreases
For the reaction,
$2 {S O}_{2} (g) + O_{2} (g) \to 2 {S O}_{3} (g)$ ,
In this case, there are 2 moles of a gas on the product side and 3 moles of gas on the reactant side. The reaction results in a decrease in the amount of gas, so the entropy change is negative.
