Option (C)

Explanation:

The Bathypelagic zone refers to the middle zone that is formed between the Mesopelagic and the Abyssopelagic zone. This covers a depth of of about 1000 to 4000 meters below the mean sea level. Sunlight cannot penetrate into this layer because of its greater depth. The pressure in this region is extremely high but still there are various types of life forms present, where the organism can survive without the presence of swim bladders and they are adapted to the conditions prevailing at that depth and able to maintain buoyancy.

Thus, the correct answer is option (C).
