Which of the following is a bio-diesel plant?

Ratanjot is the common name for Jatropha curcas (physic nut / Barbados nut). Its seeds contain about 30-40% non-edible oil that is widely used as a feedstock for producing bio-diesel, and it can grow on wastelands without competing with food crops. The other plants are aromatic or medicinal, not oil-seed bio-diesel sources: Java grass and Rosha grass (palmarosa) are Cymbopogon species cultivated for aromatic essential oils, and Guggul (Commiphora wightii) is a resin-yielding medicinal plant.
