Agave americana (century plant)-> is an example of vegetative propagation by bulbils..
Hence;option C is true...

Agave is a succulent plant that belongs to the family Asparagaceae. It is native to hot and arid regions of Mexico, Southwestern United States, and Central America. Agave reproduces vegetatively and sexually. Vegetative reproduction is the process of producing new plants from vegetative structures such as leaves, stems, roots, or buds.

Bulbils:
The vegetative reproduction of Agave occurs through bulbils. Bulbils are small bulb-like structures that develop in the axils of the flower clusters or inflorescences. These bulbils are also known as offsets or plantlets. They are tiny, round, and resemble miniature bulbs. Each bulbil has a small stem and a few fleshy leaves.

Process:
The bulbils of Agave grow on the flower stalk of the parent plant. They are produced asexually and genetically identical to the parent plant. The bulbils mature and fall off the parent plant when they are fully developed. The bulbils can then be collected and planted in the soil to grow new plants.

Advantages:
Vegetative reproduction through bulbils has some advantages over sexual reproduction. Some of the advantages are:

1. It is a rapid and efficient way of propagating Agave plants.
2. The new plants produced through bulbils are genetically identical to the parent plant. Hence, they retain the desirable characteristics of the parent plant.
3. The new plants produced through bulbils start growing rapidly from the beginning, as they have already stored food in the bulbils.

Conclusion:
In conclusion, Agave reproduces vegetatively through bulbils. This process is a rapid and efficient way of propagating Agave plants, and the new plants produced are genetically identical to the parent plant.
