In my apartment there are two rooms, is used as a living room.
A. larger one
B. the larger of which
C. the largest one
D. the largest of which

A. larger one(答案→)B. the larger of whichC. the largest oneD. the largest of which解析：由于是两个房间，即是两者比较，故宜用比较级，因此排除C和D；又由于两句之间没有连词，故不宜选A。注：若在空格前加上and 一词，则要选A。

和我的回答一样，看来我也对了
