Solution
The correct option is B Layering
Plants can be propagated vegetatively without involving the process of sexual reproduction. The vegetative propagation can be natural or artificial. With the objective of improving crops and ornamental plants, humans have devised various methods for asexual propagation of angiosperms. Most of these methods are based on the ability of plants to form adventitious roots or shoots. Cutting, layering, grafting, cloning are few such methods. The layering process refers to growth of roots by vegetative structure of stem when covered by a layer of soil.
