After the flooding, people were suffering in that area, ________ urgently needed clean water, medicine and shelter to survive.
A. which B. who
C. where D. what
【答案】B
【解析】
【分析】
【详解】考查定语从句。句意：洪灾过后，那个地区的人们正在受苦，为了生存，他们急需干净的水、药品和住所。将先行词people代入定语从句后为：people urgently needed clean water，medicine and shelter to survive，可知先行词在从句中作主语，所以排除C项；what不能引导定语从句，故排除D项；因为先行词为“人”，所以排除A项。故答案为B项。
