单选题 His desk-mate talked happily about the teachers and lessons ______ she prefers to choose for the coming term.
A. which B. who C. when D. that

【正确答案】 D

【答案解析】[解析] 定语从句题。当定语从句的先行词既含有人也含物时，定语从句的引导关系代词为that。例如：①Do you know the things and persons that they are talking about?② The bike and its rider that had run over an old man were taken to the police station．所以[D]为正确选项。
