Answer 1

Answer:

D. The edible part of ginger is a root

Thick stems that grow horizontally under the soil are rhizomes. Nodes and internodes are present in this kind of stem and the adventitious roots arise from the node. Rhizomes are unaffected during unfavourable conditions. The edible part of ginger is the rhizome i.e. the underground stem.
