The correct option is A Vegetative propagation
Vegetative propagation is a type of asexual reproduction in plants. Any part of the plant, except the flower, is involved in vegetative propagation. For example: stem, leaves, roots, etc. The offsprings are almost always identical to the parent plant. Ginger plant grows from the rhizome, a swollen fleshy portion of the stem, that grows slightly below the surface of the soil.
