Best answer
Correct option is (b) The reed-swamp

Best explanation: The sequence of successional stages occurring in water is known as hydrarch succession or hydrosere. The free-floating plants with time are replaced by the reed-swamp in a hydrarch succession. Some examples of the reed-swamp plants are Bothrioclova, Phragmites (Reed), Typha, etc.
