[Answer]-Optimal way to filter object from list of django model objects

Rather than using a set here, I would use a dictionary keyed by the question ID. (Note you don’t actually need the question itself, so you can drop the select_related.)

choice_dict = {c.question_id: c for c in Choice.objects.filter(question__in=questions).all()}
for question in questions:
     Answer(question=question,
            choice=choice_dict[question.id],
            response=response)
