Hint: The potato is a stem tuber and has nodes which consist of axillary buds, leaf scars and internodes too. They form a start for new plants.

Complete step by step answer:
-Potato is also known as Solanum tuberosum. It is a stem tuber which has a modified stem for vegetative propagation. These tubers show nodes, internodes, scale leaves and axillary buds. They store starch in their stem as their food and thus known as stem tubers.
-The potato eyes are known as nodes which are seen on the surface of the potato. It is actually made up of one or more axillary buds subtended by a leaf scar.
Under favourable conditions, the nodes have axillary buds and are developed into plants. -This is called vegetative reproduction. The stolons are grown at the site and produced etiolated stems.
-Vegetative propagation also occurs in rhizomes like ginger, turmeric, etc. Corm is an underground stem that reproduces vegetatively like found in Colocasia, Crocus, etc. The bulbs bearing a number of buds are seen in garlic and onion.

So, the correct answer is A.

Note:
The tuber has all pith, vascular zones and cortex which ideally are found in the stem. The enzyme lipoxygenase controls the development of potato tuber development.
