Solution
The correct option is A Gossypium herbaceum
Gossypium herbaceum, commonly known as levant cotton is a species of cotton native to the semi-arid regions of sub-Saharan Africa and Arabia where it still grows in the wild as a perennial shrub. Cotton is usually used as a textile while making clothing and can be made into yarns and sheets of fabric. It is also useful in paper industry. Cannabis sativa is an annual herbaceous plant in the Cannabis genus, a species of the Cannabaceae family. People have cultivated Cannabis sativa throughout recorded history as a source of industrial fibre, seed oil, food, recreation, religious and spiritual moods and medicine. Crotalaria juncea also known as sunn or sunn hemp, is a tropical Asian plant of the legume family. It is generally considered to have originated in India. It is now widely grown throughout the tropics and subtropics as a source of green manure, fodder and lignified fibre obtained from its stem. Sunn hemp is also being looked at as a possible bio-fuel. Linum usitatissimum is grown for its oil, used as a nutritional supplement, and as an ingredient in many wood-finishing products. Flax is also grown as an ornamental plant in gardens. Flax fibres are used to make linen.
Thus, the correct answer is option A.
