A where
B. who
C. which
D. that
答案：
A. where
B. who
(答案→)C. which
D. that
解析：考查引导定语从句关系词的区别。根据句意：他最好的电影是关于印度甘地的生活，这部电影获得了几个奥斯卡奖。A 关系副词，引导定语从句，定语从句不缺主语和宾语且先行词是地点名词； B 先行词指人的才能选；D that不能引导非限制性定语从句；这里提到的不是甘地获得奥斯卡奖，而是他最好的电影，这是个间隔定语从句，先行词是电影，由“was about the life of Gandhi in India”把定语从句和先行词隔开，先行词His best movie指物，且引导非限制性定语从句，故用which引导，答案C正确。
