Which of the following statements are correct in the context of energy crops?

1.They are fast-growing plants

2.They require a specific season to grow

3.They necessarily require fertile lands to grow

4.They can be converted into gaseous and liquid fuel

5.They generally have a high calorific value

A1, 4 & 5 only ✓ Correct

B1, 2, 3 & 4 only

C2, 3, 4 & 5 only

D3, 4 & 5 only

Correct answer: (A) 1, 4 & 5 only

Explanation

Energy crops are valued because they grow fast, can be converted into gaseous and liquid fuel, and generally carry a high calorific value.

Statement 1 holds, as rapid growth allows frequent harvesting of biomass.

Statement 4 holds, since they yield fuels such as biogas (biogas) and bioethanol.

Statement 5 holds, because a high calorific value makes their energy output worthwhile.

Statement 2 fails, as many energy crops are not tied to one specific growing season.

Statement 3 fails, since a major merit is thriving on marginal and degraded land rather than needing fertile soil.

Common examples include switchgrass, miscanthus, jatropha and fast-growing willow.
