选that还是选in which

选that还是选in which
Our goal is to build a harmonious society____ all people are well educated,workers well paid,patients well treated,elders well tended,and families well accommodated.
A.which B.that C.in which D.of which

in which
这是定语从句,从句中不缺成分,要填关系副词作状语.
that,which 为关系代词,故不能选.
society做先行词,这里只能用in 搭配
in this society all people are well educated,workers well paid,patients well treated,elders well tended,and families well accommodated.
