The teacher asked if ________ to bring our textbooks to class.  all we had remembered  we had all remembered  had all we remembered  had we all remembered

The correct sentence is "The teacher asked if we had all remembered to bring our textbooks to class."

Here's why:

1. The subject of the sentence is 'we'. In English, the subject usually comes before the verb. So 'we' should come before 'had remembered'.

2. 'All' is a quantifier referring to 'we', so it should be placed next to 'we'.

3. The auxiliary verb 'had' is used to form the past perfect tense, which is used to talk about something that happened before another action in the past. It should come before the past participle 'remembered'.

4. In English, in indirect questions the word order is subject + verb, not verb + subject. So 'had we all remembered' would be incorrect because it uses the word order of a direct question.

So, the correct order is "we had all remembered".
