There are two buildings,___ stands nearly a hundred feet high.为什么是d?做的成分我还不是太清楚

定语从句.which指代the two buildings,句意：有两栋建筑,其中较大的一栋建筑有一百英尺高.那c 为什么不对？that前面不能加介词，所以不能加of。只写that的话，从句就变成the larger one that stands nearly a hundred feet high，这样的话，that变成指代前面的the larger one （较大的那个建筑），that stands nearly a hundred feet high就变成修饰the larger one （较大的那个建筑）的一个定语从句，而抛开that stands nearly a hundred feet high这个从句不看，被修饰的部分the larger one 后面没有谓语，句子不完整。解释比较复杂，慢慢体会吧。C the larger one that one是介词 ？复制党~1、one 怎么会是介词呢？我没有这么说过。2、什么复制党？我没有复制。3、这个句子两种说法：（1）There are two buildings,the larger of which stands nearly a hundred feet high.(定语从句)。（2）There are two buildings and the larger one stands nearly a hundred feet high.(并列句)。4、在（1）句中，which指代the two buildings,of表示所属关系，of which相当于of the two buildings, the larger of which就相当于the larger one of the two buildings.解释完毕。
