Solution
The correct option is C
Eyes, rhizome, bulbil, leaf bud and offset
Tubers are the underground modification of stem which stores starch. It has buds on its surface which help in the growth of the new plant as these buds are meristematic in nature. The buds are also known as eye. For example, eye.
Ginger is propagated by the rhizome. It is an underground stem modification. The terminal bud of rhizome may or may not grow into an aerial shoot. The stem is differentiated into nodes and internodes. Adventitious root occurs on the lower side.
Bulbils are a small bulb-like structure which is mainly present in the axil of leaf and stem. Agave bears bulbil which falls on the ground and forms a new plant. It is present in the axil of bracts in agave. Bulbils are considered as modified vegetative and floral buds which stores food and also helps in vegetative propagation of the plants.
The multiplication of plant which takes place by the vegetative parts of the plant like stem, leaf, flower or fruit is known as vegetative propagation. Bryophyllum is multiplied vegetatively by leaves. The leaves of the Bryophyllum has notch which when falls on the moist soil, germinates into flower. The notch is meristematic in nature which has the potential to germinate into a new plant which has adventitious roots.
Water Hyacinth propagates by offsets. An offset is a short thick runner like the branch which produces a new plant at its tip. The offsets grow in all directions from the main stem of the parent plant.
So, the correct answer is option C.
