Answer 1

The correct option is B

$\begin{array}{ccc}& \text{Artificial methods}& \text{Natural methods}\\ & \text{Layering}& \text{Bulbils}\end{array}$

Layering is a type of horticultural or artificial method of vegetative propagation in which adventitious roots are induced on a soft stem while it is still attached to the plant. Bulbils are multicellular fleshy buds that take part in natural vegetative propagation, e.g., Oxalis, Agave, pineapple
