Every student in our class had an application form in his hand，but no one knew which office ________.

A．to send it to	B．to send it
C．to be sent to	D．to have it sent

答案

A

解析

根据句意及句子结构可知，选项部分不定式与疑问词一起作为句子的宾语，在这一结构中，常用不定式的主动结构，可以转换为宾语从句：but no one knew which office he would send it to。注意send sth to sb/sp为固定短语，to为介词，不能省略。
