Solution

The correct option is E All are correct
The Tapetal layer is a nutritive layer of microsporangium that provides nourishment for the developing pollen grains.
The hilum is the connection point between ovule and funicle.
In aquatic plants, like water hyacinth and lily, flowers are present above the surface of the water and they can be pollinated by insects, water, etc.
As a result of double fertilization, the primary endosperm produced will be triploid in nature by the fusion of two polar nuclei and one pollen gamete.
Thus, the correct answer is 'All are correct'.
