Among the strategies for sustainable development discussed in the chapter, which option correctly combines a strategy with its primary environmental rationale?
AMini-hydel plants in hilly regions — primarily to reduce transmission loss and avoid land-use change
BCNG in urban transport — primarily to raise government revenue through fuel cess
CBiopest control using neem-based pesticides — primarily to increase chemical pesticide consumption
DUse of LPG and gobar gas in rural areas — primarily to raise farm output
Answer & Solution
Correct answer: A. Mini-hydel plants in hilly regions — primarily to reduce transmission loss and avoid land-use change
Mini-hydel plants generate power locally, sidestepping long-distance transmission losses and infrastructure, and they do not alter land-use patterns. The other pairings invert the actual rationale: LPG/gobar gas reduce indoor pollution and protect forests; CNG cuts emissions, not raises revenue; biopest control REDUCES chemical pesticide use.
