A. whose

B. with which

C. about which

D. about whose

答案：

A. whose

B. with which

C. about which

(答案→)D. about whose

解析：考查定语从句，句意：最近一些日本人想和中国制造冲突，我们非常担心它们的意图，句子的意思是指“Recently some Japanese have been trying to make conflicts with China这件事情”的影响，attempts缺少定语，要用whose从句中使用了be concerned about的短语，effects为介词about的宾语；所以用“介词加连接代词”的形式；选D。
