The correct answer is (c) Fluorochemicals

Explanation: Fluorochemicals are widely used in paper coatings for oil and moisture resistance in microwave popcorn bags. It is also used in fast-food paper packaging for muffin and french-fry bags, sandwich/burger wrappers and small pizza and burger boxes. The perfluorocarbon moiety in these classes of products has the effect of lowering the surface energy of the individual paper fibers which greatly contributes to the holdout of low surface energy liquids such as greases and oils.
