Analysis of test questions: the appreciation of RMB against foreign currency means the depreciation of foreign currency and the decrease of foreign exchange rate. At the same time of RMB appreciation, RMB exchange rate rises. It's bad for exports and good for imports. Therefore, item C and item AB are wrong in this question. China's direct utilization of foreign capital will not necessarily increase substantially. Item d itself is correct but does not meet the meaning of the question, so it should be excluded.

Comments: This question is about the exchange rate. This formula can be used: exchange rate rise → domestic currency depreciation → beneficial to domestic commodity export (unfavorable to domestic import) → unfavorable to domestic (internal and external) investment → increasing domestic employment → increasing national income. Other statements can be converted into the above formula for derivation, which simplifies complex problems.
