Answer 1

Answer: (C)

Only the male flowers break from the plant and rise to the surface while the female flowers are brought to the surface by long pedicels

Tape grass is a submerged hydrophyte. It is a dioecious plant with the flowers borne underwater. The male flowers detach on maturity and float on the surface of the water while the female flowers grow underwater and they come up to the surface with the help of their thin long stalk.

So the correct option is C.
