Answer: Option (C) is the correct answer.
Step-by-step explanation:
Food insecurity means the state where there is no dependable access to sufficient and affordable quantity of nutritious food.
For example, a family suffering from poverty will have lack of food and therefore, not able to fulfill basic needs.
Whereas eating diets rich in meat, eating diets rich in cereal grains etc represent food security.
Thus, we can conclude that making biofuels is the practice which is least likely to lead to food insecurity.
