A
Disphotic and Aphotic
B
Aphotic
C
Mesopelagic
D
Bathypelagic
Explanation: 

Detailed explanation-1: -The animals that live in the disphotic zone are adapted to life in near darkness, cold water and high pressure.

Detailed explanation-2: -Life in the aphotic zone Unusual and unique creatures dwell in this expanse of pitch black water, such as the gulper eel, giant squid, anglerfish, and vampire squid. Some life in the aphotic zone does not rely on sunlight at all.

Detailed explanation-3: -The Disphotic Zone is found just below the Photic Zone and is known as the twilight layer. In this zone only a small amount of light penetrates the water. Plants do not grow here due to the insufficient amount of light. The darkness layer or Aphotic Zone is entirely dark meaning there is no light.

Detailed explanation-4: -Sunlight Zone This zone extends from the surface down to about 700 feet. This is where most of the visible light is and with light comes heat. This is where the wide range of temperatures occur. Most marine animals live in this zone and feed off of photoplankton (the basis of the ocean food chain) and smaller fish.
