Oil spills happen in our oceans. Some oils contain volatile organic compounds; these compounds make the oil denser. What large-scale impacts could this kind of oil spill have on the ocean environment? (3 points)

A) Oil is natural and doesn't have an overall negative impact on the ocean environment.
B) Oil that is denser will sink and have a negative impact on the ocean environment.
C) Oil that is denser will float on the ocean's surface and will have a negative impact on the environment.
D) Oil will impact only a small area of the ocean and not have a large-scale impact on the environment.
