One thing is not expensive in France is the wine!
A. what
B. what
C. where
D. that

A. whatB. whatC. where(答案→)D. that解析：句意：在法国不昂贵的一件东西就是酒。定语从句用来充当句中定语的主谓结构，被修饰的名词叫先行词，连接主从句的是关系词。关系词分：1关系代词：who , whom , whose , which , that 。2关系副词：where,when why 等。一般的who 用于指代人的先行词，which 用来指代物的先行词，that既可指认又可指物。one thing 物，故选D。
