Hint: Plant propagation is a process in which new organisms are produced by seeds, cuttings and through other plant parts. There are two types of propagation in plants which are sexual and asexual propagation. Propagation in ginger is an example of natural vegetative propagation.

Complete answer: 
An asexual method of plant reproduction that happens in its root, leaves, stem or buds is known as vegetative propagation. Vegetative propagation is two types-Natural vegetative propagation and artificial vegetative propagation. Following are the types of natural vegetative propagation.
Bulbs-Bulbs are developed from lateral buds of the mother bulb. E.g. daffodils, onion etc.
Rhizomes are the root-like stems that grow horizontally under the ground are known as rhizomes. It stores food made minerals and the lower portion of rhizomes conducts water and minerals. Examples include iris and root ginger.
Stolon -Horizontal stems which grow above the ground are stolon. The new plant becomes independent once the connection breaks from the parent plant. e.g. strawberries.
Tubers-Swollen portions of an underground stem which stores food are called tubers. Axillary buds also known as ‘eyes’ produce shoots which form a new plant. Example-potatoes.
Leaves-When leaves from the parent plant and develop into a new plant it is known as natural vegetative propagation through leaves. E.g. Bryophyllum
Artificial Vegetative Propagation is done by humans in fields and labs. It includes cutting, layering, grafting and tissue culture techniques. The vegetative propagation through the underground stem or rhizome occurs in ginger.

So, the correct answer is option B- Stem (rhizome).

Note: Tissue culture is a technique in which parts of a plant are cultured in the laboratory to develop a new plant. It is used for rare or endangered species. It’s an artificial way of propagation.
