Answer :
Final answer:
The zone that is part of the oceanic benthic zone and includes the flat area of the ocean basin floor is called the abyssal zone. Therefore the correct answer is option b.
Explanation:
The zone that is part of the oceanic benthic zone and includes the flat area of the ocean basin floor is known as the abyssal zone (Option B). The benthic zone refers to the bottom region of oceans and lakes, which includes the sediment surface and some sub-surface layers.
Within this benthic zone, the abyssal zone is a vast expanse of the ocean floor, lying at depths between about 4,000 and 6,000 meters (about 13,000 to 20,000 feet), where no sunlight penetrates, and hence no photosynthesis occurs.
