Correct Answer :- a

Explanation : Bulb vegetables are those variety of vegetables that are not eaten directly on their own, rather, they are used in food dishes to enhance the flavour of the food.The best known bulb vegetables are onion, chive, spring onion and garlic.

Unlike the potato, which is a tuber, or thickened stem, the sweetpotato that we eat is the storage root of the plant; an enlarged lateral root. The plant reproduces in three ways: from seed, from the actual storage roots, or from the plant vines. Sweetpotato is cultivated by vegetative propagation.

They are non-vascular and reproduce via spores. But the above-ground portion that we think of as a mushroom is actually the equivalent of a fruiting structure, which are produced from underground strands called mycelium. Spores are most often dispersed from slits or tubes underneath the cap.

Bryophyllum develops from buds on the modified leaves. Buds are developed on the leaf margin at notches. These when seperated grow into a new plant. 

The rapidly reproducing yeast cells by budding release carbon dioxide due to anaerobic respiration in the dough. Hence the dough rises. 

Gynoecium is the female reproductive part of the flower. The gynoecium consists of one or more separate pistils. A pistil typically consists of three parts namely stigma, style and ovary

Ovary is the expanded basal part, on which lies the elongated tube called the style. The style connects the ovary to the stigma. The stigma is present at the tip of the style and is the receptive surface for pollen grains

Flowers with stamens or roecium and pistils or gynoecium or male and female reproductive organs are called as complete flowers.
