Best answer
The correct option is (a) Hydrarch succession

Easiest explanation: The sequence of successional stages occurring in water is known as hydrarch succession or hydrosere. It usually starts with the colonization of small phytoplanktons. These organisms act as the pioneering species in hydrosere.
