Rhizome of ginger is a modification of stem because it bears nodes and internodes.
Explanation:
Rhizome of ginger is a modified stem which grows horizontally underground. It is a creeping stem which gives rise to adventitious roots from the lower surface and aerial shoots from the upper surface. The rhizome bears nodes and internodes which are characteristics of a stem. The nodes are the points from where the leaves and branches arise, while internodes are the portions of the stem between two nodes.
The rhizome of ginger also has buds which can give rise to new shoots and roots. This is another characteristic of a stem. In contrast, roots do not have buds and cannot give rise to new shoots.
Therefore, the rhizome of ginger is a modification of stem because it bears nodes and internodes, which are characteristic features of a stem.

Rhizome of ginger is a modification of stem because it bears nodes and internodes. Rhizome is a modified stem of a plant that is usually found underground, often sending out roots and shoots from its nodes. Rhizomes are also called as creeping root stalks. Rhizomes develop from axillary buds and are diageotropic or grow perpendicular to the force of gravity. The rhizome also retains the ability to allow new shoots to grow upwards.
Thus, the correct answer is option B.
