单选题 The major international auction houses (posted) annual earnings that pointed to a (healthy) art market, though (the one) not as robust as (that of) the frenetic 1980s.

A、 posted
B、 healthy
C、 the one
D、 that of

【正确答案】 C

【答案解析】[解析] 句中though及之后内容修饰a healthy art market，其中中心词为形容词：robust，为形容词作后置定语的结构，因此C项所对应的the one为多余成分。
