Correct Answer: D

Solution:

A number of organisms live in water. They are called as Aquatic organisms. Various aquatic habitats are sea (marine), estuary (estuarine), pond, lake (lotic) and river (lentic).

Bottom habitat is called as benthic, while above bottom habitat is the pelagic habitat.

Organisms confined to bottom are called as benthos. Pelagic organisms are differentiated into plankton (microscopic, drifting over surface), neuston (macroscopic, floating, or swimming on or near water surface), nektons (actively swimming inside water).
