为啥C不对呢，石油下降他的货币购买力也不行了吧

问题如下：

A country with a developed economy maintains its own currency, NLC, and has domestically produced oil and natural gas as its most important exports. In a recent stress test of the country’s banking system, several scenarios were considered. Which of the following is most consistent with being part of a coherent scenario?

选项：

A.An increase in domestic inflation and appreciation of the NLC

B.A significant increase in crude oil prices and a decrease in the country housing price index

C.A drop in crude oil prices and appreciation of the NLC

D.A sustained decrease in natural gas prices and a decrease in the country’s stock index

解释：

A scenario is coherent when a change in one factor influences other factors in a logical manner. In this case, choice d is a coherent scenario since the country’s economy depends heavily on exports of oil and natural gas, so therefore a sustained decrease in natural gas prices should lead to a decrease in stock prices as the domestic economy weakens. In stress testing banks, it is often challenging to develop scenarios where all factors behave coherently.
