class AuthorSerializer(serializers.ModelSerializer):
    class Meta:
        model = Author
        fields = ['id', 'name']

author = Author(id=1, name='Alice')

Step 1: Understand ModelSerializer output
ModelSerializer converts model fields to a dictionary with field names and values as expected types.
Step 2: Check fields included
Fields 'id' and 'name' are included, so both appear in output with correct types.
Final Answer:
{'id': 1, 'name': 'Alice'} -> Option A
Quick Check:
Serializer data = dict with fields and values [OK]

Quick Trick: Serializer.data returns dict with model fields and values [OK]
