Read the passage below carefully:
'The accumulation of cassava peels from smallholder processing mills across southwestern Nigeria has long posed severe environmental disposal challenges, polluting local waterways through toxic cyanogenic leachate. However, recent agricultural biotechnology initiatives have transformed this agricultural waste into high-grade biochar and animal feed supplements. By fermenting the peels with specific fungal isolates, processors not only neutralize dangerous hydrocyanic toxins but also enrich the crude protein content of the residual biomass. Consequently, rural farming clusters are converting a hazardous pollutant into a cost-effective livestock supplement, simultaneously improving community sanitation and reducing reliance on expensive imported feed concentrates.'
Which of the following options best captures the central argument of the passage in a concise summary?
- AFungal isolates are specifically cultivated by rural processors to neutralize dangerous hydrocyanic toxins found in cassava residue.
- Biotechnology-driven fermentation turns toxic cassava waste into nutritious livestock feed, resolving environmental pollution while cutting feed costs for rural farmers.Cevap
- CSouthwestern Nigerian farmers have completely replaced imported feed concentrates with locally produced cassava biochar.
- DSmallholder processing mills are being shut down due to the extreme environmental damage caused by cyanogenic leachate in local waterways.
