The correct choice is (b) Ceratophyllum

The explanation is: Ceratophyllum is a fresh water plant (submerged) which bears male and female, both, flowers on the same plant. A male flower has several (30-45) stamens. The mature anthers breaks, and rises upward and dehisce occurs on the surface. The pollen grains are round, with no exine. The pollens come in contact with long and sticky stigmas for pollination.
