Which one of the following is being utilized as a source of biodiesel in the Indian countryside?
A Beetroot
B Sugarcane
C Pongamia
D Euphorbia

Detailed Solution

Biodiesel is a renewable fuel obtained from vegetable oils by transesterification.
Pongamia pinnata (pongam or karanja) is a leguminous, nitrogen-fixing tree whose seeds contain 30-40 percent oil.
It is commonly planted as an ornamental and shade tree, and in the Indian countryside its seed oil is being used as a source of biodiesel.
Jatropha is another important biodiesel plant.
Sugarcane and beetroot are sources of sugar, which is fermented to give ethanol (bioethanol), not biodiesel.
Euphorbia species are petrocrops that yield latex rich in hydrocarbons, but they are not the source being utilised for biodiesel in the countryside.
So the answer is Pongamia.
