When you want to introduce yourself to an american,you can just try a _____,such as "Hello,my name is ..."
A.commonly used greeting
B.used commonly greering
C.commonly using greeting
D.using commonly greeting
为什么选A呢?

.....commonly used greeting 用一个常用的招呼语做开头
(副词)( 被用来)

commonly is an adverb and this adverb modifies greeting. And this greeting is used rather than unused.

greeting 是名词,肯定放在最后这个不用说吧
就是看前面两个修饰的定语,谁先谁后了.
used 看句子成分,used 是修饰greeting的
而commonly 则是修饰 used greeting的
