Question

Which one is not a petrocrop?

• A. Euphorbia lathyrus
• B. Calotrophis Procera
  
• C. Jatropha
• D. Hardwickia binata

Answer 1

The correct option is D

Hardwickia binata

Petro-crops are plants that produce latex, containing long chain hydrocarbons, which can be converted into biofuels and used as alternatives in place of petrol or other engine fuels. Euphorbia lathyrus and Calotrophis procera produce latex which is converted into biofuel that has similar composition of hydrocarbons like that of crude oil or other fuels. Jatropha seeds produce oil which is converted into biodiesel and used as an alternative for engine fuels.

Hardwickia binata, commonly known as anjan, is a deciduous ornamental tree.

So, the correct answer is 'Hardwickia binata'.
