Solution
The correct option is B Nelumbium
Nelumbium is a hydrophytic plant with large floating leaves on the upper surface. It has stomata on the upper surface. If the surface is coated with wax, transpiration will stop. Consequently, water and minerals will not be able to enter the plant. Hydrilla, Vallisneria and Utricularia are submerged hydrophytic plants, which absorb water and minerals through the general surface and do not depend on transpiration to absorb water and minerals.
