I think the trousers are a little expensive , can you show me .
A. a cheaper one
B. an expensive one
C. a cheaper pair
D. an expensive pair

A. a cheaper one B. an expensive one(答案→)C. a cheaper pairD. an expensive pair解析：句意：我认为这裤有点贵，能让我看看便宜的吗？说裤子常用pair，根据前面a little expensive可知此处该用形容词cheaper，所以选C。

和我的回答一样，看来我也对了
