Question

The largest leaf belongs to
A. Nerium
B. Nicotiana
C. Victoria
D. Rafflesia

Answer 1

Hint: The largest leaf belongs to a genus of water lilies from the plant family Nymphaeaceae with enormous green leaves that lie on the surface of the water. It has left up to three meters in diameter on stems up to eight meters long. The genus name was given in honour of Queen (she is also a carrier of haemophilia) of the British Empire.

Complete answer:
Let's for answering the question study about each option one by one
Nerium - Cerium oleander, most commonly known as Nerium or oleander is a shrub or small tree in the dog family Apocynaceae. It is so broad that its exact region of origin has not been identified, although it is usually associated with the Mediterranean. The oleander has erect stems that spread outward as it ripens. The leaves are paired or triangular, thick and leathery, dark green, thin lanceolate, with full edges, filled with small nets, typical of Eudicot. The leaves are light green and very shiny when young before ripening to a dull dark green.
Nicotiana- Nicotiana is a genus of herbaceous plants and shrubs in the Solanaceae family native to America, Australia, South-West Africa and the South Pacific. Various species of Nicotiana often referred to as tobacco plants, are grown as ornamental gardens. N. tobaccum is grown all over the world for production of tobacco leaves for cigarettes and other tobacco products.
Victoria- Victoria (water lilies) belongs to the plant family Nymphaeaceae with enormous green leaves that lie on the surface of the water. Nymphaeaceae. It is the national flower of Guyana. Victoria Amazon has very large leaves, up to three meters in diameter, carried on a submerged stalk for seven to eight metre in the water surface. This is the largest water lily in the world. V. amazonica comes from shallow waters in the Amazon basin such as lakes and bays. It can take up to forty-eight hours for the flowers to fully bloom. The flowers are white the first night when they open and turn pink the second night. They have a diameter of up to forty centimetres and are pollinated by beetles. This process is described in detail by Sir Gillian Prans and Jorge Arius. This species used to be named Victoria Regia after Queen Victoria, but its name has been changed. He is depicted with the coat of arms of Guyana.
Rafflesia- Rafflesia is a genus of parasitic flowering plants from the Rafflesiaceae family. This species has very large flowers, the shoots of which protrude from the ground or directly from the rootstock of the host plant; One species has the largest flowers in the world. It is a holoparasite of the genus Tetrastigma (vitamin plant, grape family) that propagates its absorbent organ, the haustorium, into the tissues of the vine. The only parts of the plant that can be seen outside of their host vines are the five-coloured flowers.
So, the correct answer is “Option C”.

Note: Victoria leaves can withstand a considerable amount of weight due to the structure of the plant, although the leaves themselves are quite delicate: such that "a straw that is caught six inches above and falls perpendicular to it can easily penetrate them". To overcome the fragility of the panels, the weight must be distributed to the surface by mechanical means such as plywood. This allows the leaves to hold up to thirty-two pounds.
