B

C
Runner
D
Corm
Explanation: 

Detailed explanation-1: -description. In botany a stolon-also called a runner-is a slender stem that grows horizontally along the ground, giving rise to roots and aerial (vertical) branches at specialized points called nodes. In zoology, stolons of certain invertebrate animals are horizontal extensions that produce new individuals by budding.

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: -Rhizome is also called creeping root stalk. It is a horizontal form of plant stem that grows underground which can form roots and shoots that grow into a new plant. Plants store starches and proteins in rhizomes and can survive unfavorable conditions by making use of this storage.

Detailed explanation-4: -(Bermudagrass has rhizomes that develop and remain close to the soil surface and therefore some call them stolons.) A stolon is a segmented, horizontal stem which remains chiefly above ground. Stolons also arise from an adventitious bud in the crown zone. The segmented stem is covered with scales (modified leaves).

Detailed explanation-5: -Stolons are often called runners. Imprecisely they are stems that run atop or just under the ground; more specifically, a stolon is a horizontal shoot from a plant that grows on top of or below the soil surface with the ability to produce new clones of the same plant from buds at the tip.
