Answer: (B)

Verified step by step guidance

1. Understand the different zones in an aquatic environment: The aquatic environment is divided into different zones based on light penetration and depth. These include the photic zone, aphotic zone, benthic zone, and abyssal zone.
2. Define the photic zone: The photic zone is the upper layer of a body of water that receives enough sunlight to support photosynthesis. This is where most photosynthetic organisms, like algae, are found.
3. Define the aphotic zone: The aphotic zone is the deeper layer of water that does not receive enough sunlight for photosynthesis. Organisms here rely on other sources of energy.
4. Define the benthic zone: The benthic zone refers to the bottom of a body of water, including the sediment surface. It can be in both photic and aphotic zones, depending on the depth.
5. Define the abyssal zone: The abyssal zone is a deep part of the ocean, typically very dark and cold, where sunlight does not penetrate, making it unsuitable for photosynthesis.
