Bryophyllum produces plantlets along the margins of its leaves. When they mature, they drop off and root in any suitable soil beneath thereby performing the function of vegetative propagation.
Thus, the correct answer is option (A), 'Leaf'.

When the buds arises on the leaves they are called as epiphyllous buds, e.g., Bryophyllum. Epiphyllous budding is a unique mode of vegetative proliferation in restricted plant species. Leaf detachment induces activation of these buds which then develop into plantlets by differentiating roots and shoot. Leaf detachment not only induces bud differentiation but also concurrently triggers foliar senescence. Inflorescences and vegetative shoots arise from epiphyllous buds on the adaxial surface of the rachis between the pinna pairs.

Thus, the correct answer is option (C), 'Leaf'.

Turmeric reproduces via rhizomes, which are modified underground stems.

A loose bulb, where the scales are not tightly packed or tunicated, is often referred to as a scaly or false bulb in botanical terminology.

Vegetative propagation is the growth and development of the plant by asexual means. It occurs from specialized vegetative plant parts. It is made possible by meristem tissue that is commonly found within stems and leaves, as well as at the tips of roots and stems. Meristem tissue contains undifferentiated cells that actively divide by mitosis allowing plant growth.

Populus and Dahlia's plants have the apical meristematic tissue at the tip of their roots.Populus has long roots while Dehlia has tuberous roots.The meristematic tissue cells have the capacity to divide actively and form a new plant in favourable conditions.

Albizia belongs to family fabaceae. In Albizzia, vegetative propagation take place with the help of nonfleshy roots. The non fleshy roots develop adventitious buds which grow to form new plants.
