Solution

The correct option is C Hydrophytes
Hydrophytes are water loving plants and grow in aquatic environments. In these plants mechanical tissue is absent. Xylem is poorly developed or absent. Hydrophytes possess special air storage parenchyma, called as aerenchyma. It makes plant parts light, spongy and flexible and helps it float in water. Example, Nymphea, Hydrilla, Vallisnaria etc
So, the correct answer is 'Hydrophytes'
