选项 A、An area of low conservation value and low financial value.
B、An area of low conservation value but high financial value.
C、An area of high conservation value and high financial value.
D、An area of high conservation value but low financial value.

答案D

解析 首先要理解题干中的cost-effective的意思,该词意为“划算的,有成本效益的”。文章第3段第2句提到Fuller建议应把值钱但保护价值低(expensive land of low conservation value)的区域卖掉。由此可推断,与此相反的“效率最高的”保护区应该是便宜但保护价值高的区域。因此,本题应选D。
