Answer 1

Hint: Opuntia, commonly referred to as prickly pears, is a genus of the cactus family, Cactaceae. Prickly pears are often recognized for the pads from the Nahuatl word nōpalli, or nostle, for the fruit from the Nahuatl word nōchtli; or paddle cactus, such as tuna (fruit), sabra, nopal (paddle, plural nopales).

Complete answer:
For the storage of food such as potato, ginger, turmeric, etc., some underground stems are modified. Axillary buds develop spirally coiled stem tendrils in some plants and help plants ascend in gourds such as cucumbers, pumpkins, watermelons, and grapevines. Axillary buds in some plants are modified into woody and pointed thorns that shield the plant from animals. Thorns are present in many species, such as Bougainvillea citrus. Some plants in arid regions turn their stems into flattened structures (Opuntia) or fleshy cylindrical structures (Euphorbia). They produce and perform photosynthesis with chlorophyll.
The potato is a vegetative plant part, it the tuber belonging to the family Solanum tuberosum plant, and the plant itself is a perennial in the Solanaceae family of nightshades. Wild potato species can be found in the Americas, from the United States to southern Chile, originating in modern-day Peru.
In the spurge family (Euphorbiaceae), Euphorbia is a very large and diverse genus of flowering plants, commonly called spurge. 'Euphorbia' is sometimes used in ordinary English to refer collectively, not just to members of the genus, to all members of the Euphorbiaceae (in deference to the type genus).
Cucumber (Cucumis sativus) belongs to the family Cucurbitaceae gourd, it is most commonly cultivated as a creeping vine that has cucumiform fruits, which are consumed as vegetables. There are three primary cucumber varieties within which many cultivars have been produced, slicing, pickling, and burpless/seedless.

So, the correct answer is ‘A-3, b-5, c-4, d-2, e-1’.

Note:
Various types of subterranean stems include:
-Bulb-Small, upright leaves of the organ, modified into thick scales of flesh. Daffodils, tulips and lilies.
-Corm-Small roots, upright, rough or fleshy, covered with thin, dry leaves of paper.
-Rhizome-With a reduced leaf size. The top can create leafy stems, while the bottom can generate roots.
-Stolon-The ends build new plants with horizontal stems that run at or just below the soil surface with nodes that root and long internodes. They are called "runners" when they are above ground.
-Tuber-An inflated fleshy end of a stem, usually from rhizomes, but also from thickened roots as well.
