Answer 2

Organisms form carbon film when sediments cover the organisms and decay of organisms form hollows.

EXPLANATION:

When an organism is covered by sediment, it begins to decay. When decaying, the organisms release a gas. This process in turns leaves a thin film of carbon that preserves parts of the organisms.

The hollow that forms on the sediment is the carbon film that contains what are called fossils of the organism.  Thus, option C is correct.
