Solution

The correct option is A 1 only
Explanation:

Second Generation Biofuels utilize inedible parts of the plant such as stems and husk to produce biofuel. These fuels usually require biochemical or thermochemical conversions during production. Eg. Biodiesel. These biofuels do not affect the food economy, however, their production process is quite complicated.

Jatropha is multi-purpose non-edible oil and is used as a second-generation biofuel. This is a hardy and drought-tolerant crop that can be raised in marginal lands with lesser input.

Sugarbeet and Sugarcane are food crops and are considered as 1st generation biofuels.
