The correct option is (d) Marsh-meadow
 
The best explanation: The sequence of successional stages occurring in water is known as hydrarch succession or hydrosere. The reed-swamp with time is replaced by the marsh-meadow in a hydrarch succession. Some examples of the marsh-meadow plants are  Caltha, Gallium, Mentha, Cicuta, etc.
