Answer 2

This blank can be filled with the word 'had you to sign'

So, option (3) is correct and correct sentence will be:-

How many documents had you to sign, yesterday?

Had is past form of have. It is used in past perfect tense.

We can detect whether the sentence is in present, past or future by looking the sentence structure.

Here, yesterday is used so sentence is in past tense.

Hence, V3 form of helping verb will be used with question type sentence structure.
