Answer 1

Answer: (A)

A- (I), B- (II), C- (III), D- (IV)

The Chironomid larvae are the zooplanktons, belonging to the family of nematoceran flies.
Neuston is the collective term for organisms that float on the top of water. Daphnia is a neuston.
Nekton are the aquatic organisms that are able to swim and move independently of the water currents. Example, water spiders.
Benthos are those organisms that are found on the bottom, or in the bottom sediments of a lake or sea. Ranatra is one such example.
Thus, the correct answer is option (A).
