D) Canna

Answer 1

Corm, bulbo-tuber, or bulbo-tuber is a small, vertical, swollen underground plant stem that serves as a storage organ used by certain plants to survive the winter or other adverse conditions such as summer drought and heat (perennial).

Complete Answer:

Corm, vertical, fleshy, underground stem that serves as a food-storage framework in some seed plants. It bears membranous or scaly leaves and buds, and, unlike bulbs, they do not appear as visible rings when the corm is split in half.
Corms have a fibrous covering known as a tunic, and the roots grow from a smooth base region known as the basal plate.
Corms store starches to fuel growth and help plants survive unfavourable conditions, and several contain offshoots known as daughter corms or corms that are used for vegetative reproduction.
Typical corms are crocus, gladiolus, and taro. The largest corm is the titanium arum (Amorphophallus titanum), which can weigh around 70–90 kg (154–200 pounds); the structure provides the energy required for the rapid growth of the enormous inflorescence of the plant.
Titan arum grows out of an underground stem called a corm. Corm is a type of starchy tuber that anchors the plant and stores food for the plant.
Bananas and shamrocks are also grown from corms.
Titan Arums have the largest corms of any plant in the world, reaching more than 200 pounds in some old plants.
The Indonesian people are collecting the corms to feed.

Hence the correct answer is option (C) Arum.

Note: The most thrilling event in the life cycle of the Titan arum is its blooming event. It starts with the flower budding from the corm. It looks like a leaf spike, but it has a more dimpled base. This bud starts to grow 4 to 6 inches a day. The leafy bract, covering the bloom, wilts and begins to shed. A tall spadix grows up, and as the bract sheds, there is a rough green spade surrounding the spadix. Approximately two weeks into the process, the growth slows, and the spathe turns a maroon colour and begins.
