C Correct answer
Explanation

The amount of alcohol production per hectare of given crop is:

Potato - 396 gallons

Sugarcane - 662 gallons

Sugarbeet - 714 gallons

Tapioca - 410 gallons

Hence, maximum alcohol production is by sugarbeet.

So, the correct answer is 'Sugarbeet'.

D Correct answer
Explanation
Energy cropping is the cultivation of those plants which can be harvested to produce ethanol or bioethanol that can be used as a biofuel. Energy crops include sugarcane, sugarbeet, cassava (Tapioca), wheat, maize etc. Euphorbia is not an energy crop. Instead, it is a petro-crop or petroleum plant because it produces latex that has long chain hydrocarbons. This latex can be converted into biofuels and used as a substitute for petrol and other fuels.
So, the correct answer is 'Euphorbia'.

Which one is being tried in India as biofuel substitute for fossil fuels?

  1. <p>Jatropha</p>

  2. <p>Musa</p>

  3. <p>Aegilops</p>

  4. <p>Azadirachta</p>
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Biofuels are the substances which are of biological origin and can be used as a source of energy. Jatropha has been used as a biofuel in India. The seeds of Jatropha contain an inedible oil which can be converted to biodiesel. The seed cake (residue left extraction of oil from seeds) can be used as fertilizer or food for cattle. The biodiesel of Jatropha oil emits 80% less carbon dioxide on burning than other fuels. So, the correct answer is 'Jatropha'.
