您好，原句应该是：

We consider__________ the machine should be adjusted each time it is used.

其中B、C句型错误，首先排除。

如果是A
we consider that 后面加从句，应该这样的
we consider that it is necessary that the instrument should be adjusted each time it is used.
因此that it necessary 不能成为从句。

另外，补充一下，consider it +adj. that （+从句） 或 +  to do sth 很比较常用的同位语句式
还有 think it adj. that / to do 等等

因此，选D。这个it是形式宾语，that所带才是真正地宾语。

再补充说明一下，（不针对任何人） it = the instrument should be adjusted each time it is used

选D。这是it做形式宾语的情况，真正的宾语是后面的that从句。
主语+动词+it+形容词+to do/that 从句。

完整句子应该是it做consider后的形式宾语的 选d
