Is there anything I can help you?

A. that

B. which

C. who

D. what

答案：

(答案→)A. that

B. which

C. who

D. what

解析：句意：有我能帮助你的事情吗？关系代词在从句中作主语、宾语。但在下列情况下一般只用that而不用which ：先行词本身是all , everything , something , nothing , anything等不定代词时， 先行词已有序数词或形容词的最高级或the last, the only等作定语时，先行词既有人又有物时。

先行词是不定代词，连接词用that,故选A。
