Answer 1

Knol-khol's edible part is knob, which results from a thickening of the tissue present above the cotyledons.

Complete Answer:
- Knol-khol falls under family Cruciferae and its botanical name is B.oleracea L. var. gongylodes. In Hindi knol-khol or kohlrabi is regarded as gobi ganth.
- Kohlrabi is a mixture of German words, meaning 'kohl' for cabbage and 'rabi' for turnip. Hence the term kohlrabi implies cabbage with the appearance of a turnip.
- Knol-khol is a hardy crop found in cool northern European climates. Knol-khol is not grown anywhere in the world on a wide scale. It is grown primarily in the region of Mediterranean, North America, Western Europe, Japan, Near East, and India.

Now, let us find the solution from the options-
- Edible portion of knol-khol is named knob which is the swollen stem.
- The leaves emerge from the knob surface.
- The stem's fleshy, turnip-like enlargement grows completely above the ground.
- This knob is harvested as raw and cooked potato, for human consumption.

Thus, the correct answer is option (D) stem.

Note: Leaves are set like swollen structure on this bulb. The conductive vessels which supply the leaves create hard inedible tissue.
