问题补充：

— it is to have a close match after a days work!

— I think so.

A. How funny

B. What a fun

C. What fun

D. How an exciting

答案：

A. How funny

B. What a fun

(答案→)C. What fun

D. How an exciting

解析：句意：一天的工作之后举行一场势均力敌的比赛是多么有趣呀！我也这样认为。感叹句有两类，一类以what开头，强调名词，一类以how开头，强调动词、形容词或副词等，fun是一个不可数名词，所以选C。
