A) littoral zone.
B) limnetic zone.
C) profundal zone.
D) benthic zone.

The benthic zone is the bottom layer of a lake or stream, which supports various organisms such as worms, clams, and other benthos. The littoral zone is the shallow area along the shoreline that is usually covered in vegetation. The limnetic zone is the open water area of a lake or pond, typically inhabited by planktonic organisms. The profundal zone is the deeper part of the lake or pond where sunlight cannot penetrate, and the water is often low in oxygen. The abyssal zone is the deepest part of the ocean, which is characterized by extreme pressure, cold temperatures, and total darkness.
