A. What a great progress
B. What great progress
C. How great progress it is
D. How great a progress it is
答案：
A. What a great progress
(答案→)B. What great progress
C. How great progress it is
D. How great a progress it is
解析：感叹句主要有what和how构成：
1、what修饰名词或名词短语，有以下两种形式： 1. What+a(an)+（形容词）+单数可数名词+主语+谓语！或是：What+名词词组+主语+谓语！ 2. What+(形容词）+可数名词复数或不可数名词+主语+谓语！
2、How引导的感叹句。 how用来修饰形容词、副词或动词。其结构是：How+形容词（副词）+主语+谓语！
本题中progress是可数名词，联系下文he has made，可知选项ACD结构有误，故选B。
