C Correct answer
Explanation

Biomass : Energy comes from living things like wood, animal wastes. Biomass does not produce pollutants like coal and petroleum does as it is completely organic. But burning of it still produce pollutants.

Fuel obtained from biomass are:

  1. Charcoal (from wood).

  2. Bio-gas from animal waste (cow-dung etc).

  3. Bio-diesel (from sugar cane and oilseed crops).

  4. All of above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Biomass is a organic fuel.Charcoal is obtained from burning of the wood. Biogas is obtained from organic wastes such as animal excreta, agricultural waste etc, Bio-diesel can be obtained from oil seed crops such as Jatropa.
