Question Statement:
Passage: 'Adoption of solar-powered micro-irrigation systems in arid regions has not only elevated water use efficiency but has also stabilized smallholder farmer incomes by reducing recurring fuel expenditures.

Which of the following can be most reasonably inferred from the passage?
Options:
- (A) Solar irrigation systems are economically viable for small farmers only with financial subsidy support
- (B) Conventional diesel pumps are cheaper in operating lifecycle cost than solar pumps
- (C) Arid regions are unsuitable for solar radiation harvesting
- (D) Smallholder farmers prefer diesel pumps due to higher reliability
