The correct option is D Corm
An underground stem axis with swollen base and enclosed by dry scale like leaves is called as corm. The corm is a solid modified stem that has few fleshy leaves. It is a swollen stem which stores food to survive winter, summer drought and heat. It is also called as bulbotuber. It is covered with scale leaves or tunics. It is consist of one or more internodes. The node is the point where the leaf attaches to the stem. In addition to normal fibrous roots, corms and some non-tunicate bulbs have special roots. Because new corms develop on top of old, they are closer to the soil surface.
Thus, the correct answer is option D.
