In an ocean floor where there is little or no penetration which cause darkness, the organisms adapt through?

The correct answer is C. In the deep ocean, where there is little to no light penetration, organisms cannot rely on sight. Instead, they adapt by developing well-developed sense organs to navigate, find food, and detect predators. These senses can include enhanced touch, smell, hearing, or the ability to detect pressure changes. Some also use bioluminescence to create their own light for communication or hunting.
