How to filter queryset for serializing a nested serializer using instance in django rest framework?

[Rahul Sarma]

My serializers.py file:

from rest_framework import serializers

    from diagnosisApp.models import Question, Option


    class OptionSerializer(serializers.ModelSerializer):

        class Meta:
            model = Option
            fields = ('id', 'content')


    class QuestionSerializer(serializers.Serializer):
        content = serializers.CharField()
        options = OptionSerializer(
            Option.objects.filter(optiongroup__question=**insert instance value here**).distinct(),
            many=True
            )

I'm trying to create a nested OptionSerializer inside QuestionSerializer but I need to filter the queryset based on the question instance which will be passed during initialization in this section: `optiongroup__question=**insert instance value here**`. How do I do this?

P.S: Please don't tell me to use ModelSerializer or SerializerMethodField because options is not directly related to Question and the options field needs to be writable.
