Right answer is (b) Rooted-submerged plants
 
The explanation: A hydrarch succession starts with the colonization of small phytoplanktons. These phytoplanktons, later with time are replaced by rooted-submerged plants in a hydrarch succession. Some examples of the rooted-submerged plants are Ceratophyllum, Chara, Elodia, Potamogeton, etc.
