The correct option is C Vegetative propagation in banana occurs by bulbil.
Vegetative propagation is a form of asexual reproduction that occurs only in plants. In this, a new plant grows from a fragment of the parent plant or a specialized reproductive structure. These specialised structures are called vegetative propagules. Vegetative propagules include structures like runner, rhizome, sucker, tuber, offset, bulb, buds which are capable of giving rise to new offspring. Since vegetative propagation is a type of asexual reproduction, the offspring produced by this method are morphologically and genetically identical to one another and their parents, hence are called clones
Vegetative propagation in banana occurs by rhizome. It is a horizontal underground stem that gives out both shoots and roots.
Bulbil is the vegetative propagule of Agave. It is a small bulb-like structure produced in the place of a flower or in a leaf axil, and having the ability to develop into a new plant.
