Which of the following is an example of lotic water body?

The correct answer is Option (3) → River

Lotic comes from the Latin lotus, “washed”, and describes flowing fresh waters — springs, streams and rivers — where the current keeps the water well aerated and mixed.

Ponds, lakes and reservoirs hold standing water and are therefore lentic systems, which stratify into distinct littoral, limnetic, profundal and benthic zones.
