A. What beautiful

B. What abeautiful

C. How beautifully

D. How beautiful

答案：

A. What beautiful

(答案→)B. What abeautiful

C. How beautifully

D. How beautiful

解析：句意:多么美丽的一座城镇啊！这是一个感叹句，常用what 和how 引导，what a/an 形容词+名词或what 形容词+名词；how 形容词+a/an +名词或how 形容词或副词。根据他们的用法可知这里选B。如果换成how，则应该是how beautiful a town it is!。
