Solution
The correct option is A Indigofera tinctoria
Indigofera tinctoria, also called true indigo, is a species of plant from the bean family that was one of the original sources of indigo dye. It has been naturalized to tropical and temperate Asia, as well as parts of Africa, but its native habitat is unknown since, it has been in cultivation worldwide for many centuries. Today, most dye is synthetic, but natural dye from I. tinctoria is still available, marketed as natural colouring. The plant is also widely grown as a soil-improving ground cover. Dye is obtained from the processing of the plant's leaves. They are soaked in water and fermented in order to convert the glycoside indican naturally present in the plant to the blue dye indigotin. Thus, the correct answer is option A.
