D
Bulb.
Explanation: 

Detailed explanation-1: -A rhizome is the main stem of the plant that runs underground horizontally. A stolon is similar to a rhizome, but a stolon sprouts from an existing stem, has long internodes, and generates new shoots at the end, such as in the strawberry plant.

Detailed explanation-2: -rhizome, also called creeping rootstalk, horizontal underground plant stem capable of producing the shoot and root systems of a new plant. Rhizomes are used to store starches and proteins and enable plants to perennate (survive an annual unfavourable season) underground.

Detailed explanation-3: -A rhizome is a modified stem that grows horizontally underground; it has nodes and internodes. Vertical shoots may arise from the buds on the rhizome of some plants, such as ginger and ferns.

Detailed explanation-4: -Underground stems are modified plant parts that derive from stem tissue but exist under the soil surface. They function as storage tissues for food and nutrients, in propagation of new clones, and in perennation (survival from one growing season to the next). Types include bulbs, corms, rhizomes, stolons, and tubers.

Detailed explanation-5: -Rhizomes are just one of the many types of modified stems. Other modified stems are bulbs, stolons, and corm. However, each has distinct features.
