Solution
The correct option is D Vallisneria
Succession is the change in the species structure of an ecological community. Hydrosere is primary succession sequence, which results in the conversion of the water body and its community into a land community. As the water body becomes shallower, more submerged rooted species are able to become established due to increasing light penetration in the shallower water. This is suitable for growth of rooted submerged species, such as Myriophyllum, Vallisneria, Elodea, Hydrilla, and Ceratophyllum. These plants root themselves in mud. So, the correct answer is option D.
