The correct option is A Stem

Modified stems are derived from stem tissue that exists under the soil surface. Various modified stems are tuber, bulb, corm, stolon and rhizome. Tuber is a thickened part of a stem which grows underground. Tubers have bud from which a new plant can arise by vegetative propagation. Potato is a modified stem called a tuber. It stores a large amount of edible starch which is used as food.

The bulb is a modified stem with leaf bases that function as food storage.

Stolon is horizontal modified stems that run below the soil surface.

Thus, the correct answer is option A.
