C. Railway creeper
D. Betel

Answer 1

Hint: Twining plants are plants with tactile buds that wrap-around supports such as ropes and upward-growing pillars. So it's important to have some kind of climbing device. You cannot grow these types of plants without spinning. The folded buds/stems become very pretty after a few years, but they can wreak havoc on supports, especially even the most energetic twin rock climbers such as wisteria.

Complete answer:
Twiner- The stem is long, flexible and soft. It can be wrapped around vertical supports such as ropes (like lablab, ipomoea, and convolvulus). Depending on the direction of winding, they are of different types of sinistrorse and dextrose.
Twining plants are herbaceous or woody plants that can be lifted higher or lower above the ground by tying the stems around the supports. This feature allows twin plants in shady forests or lush meadows to illuminate their leaves better. Twining plants twine around the stems of neighbouring plants due to the rotational movement of the shoots, which is caused by the rapid growth outside the shoots. The growth points of twin plants move to the left, counter clockwise (for most twin plants such as legumes and algae). Sometimes the direction of the spiral can change (for example, bitter jam). Convolvulaceae, Asclepiadaceae, Papilionaceae and other families have many Twining plants.
Railway creeper is found in gardens, villages, and on practically every railway station, thus earning for itself its nickname. This morning the glory vine is beautiful, climbing on to whatever it finds – the purple flower studded vine wrapped around bending bamboo stems, is a pleasing sight. Its stem is hairless, readily set roots when in touch with the earth. Seed with wispy hairs attached. Spread by wind, water, and humans.
Pea, cucumber and betel all these plants have characteristics of twiner.

Hence, the correct answer is option (C).

Note: Twining plants are often mistakenly referred to as climbing vines, simply by securing them with fibres, hair, etc., rather than wrapping them. Both groups of plants are called lianas. Surplus plants are used to plant and place garlands along walls, gazebos, fences, terraces, windows and arches. Several types of Twining plants are used as pots to decorate residential, industrial and other premises. Poles, wires or ropes are used as supports for knitting plants. Perennial Twining plants usually reproduce by vegetative means, such as shrubs, layering, and cuttings. Annual plants grow from seeds and seedlings.
