I’ll take you to a newly opened market ________ you may get all ________ you need．
A.which; thatB.where; thatC.in which; whichD.where; what在线课程B
解析：
本考题中含有两个定语从句。第一个定语的先行词是表示地点的词a newly opened market，并且从句中主语或宾语成分完整，故只用关系副词where引导，在从句中作状语，相当于in which。第二个定语从句的先行词为不定代词all，此外定语从句中谓语动词need后需要宾语，所以选用that(可省略)，不用which。
