I saw a woman running toward me in the dark. Before I could recognize who she was, she had run back in the direction ______ she had come.

A.of which

B.by which

C.in which

D.from which

答案及解析： D

解析：

句意：黑暗中，我看到一名妇女朝我跑来，我还没有来得及认出她是谁，她就朝来时的方向跑了回去。此题考查介词+关系代词which引导的定语从句，先行词为direction，代入后面的定语从句为she had come from the direction。故D项正确。
