Correct Option (B)
The passage explicitly states that "Energy crops, if not managed properly, compete with food production and may have undesirable impacts on food prices." This directly indicates that promoting the cultivation of energy crops can lead to food security problems by diverting agricultural land from food production and potentially increasing food costs.
Incorrect Options:
-
Using agricultural and forest residues as feedstock for power generation:
The passage identifies agricultural and forest residues as a source for biomass fuel. However, it highlights challenges related to their long-term reliable supply, logistical constraints, and collection costs. The text does not suggest that utilizing these residues for power generation would lead to food security issues.
-
Using biomass for carbon capture and storage:
The passage mentions biomass-based carbon capture and storage as an unproven technology intended for achieving negative emissions. While its technological readiness is questioned, the text does not establish any link between this process and food security problems.
