单选题 Every student in our class had an application form in his hand, but no one knew which office _____.A.to send it toB.to send itC.to be sent toD.to have it sent

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。

对的，就是这个意思
