Given this model and serializer, what will serializer.data output?

class Author(models.Model):
    name = models.CharField(max_length=100)

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

author = Author(name='Alice')
serializer = AuthorSerializer(author)

A{'name': 'Alice'}

B{'author': 'Alice'}

C{'name': None}

Step-by-Step Solution

Solution:

Step 1: Understand serializer.data output

Even if the instance is not saved, serializer reads the attribute value directly.
Final Answer:
{'name': 'Alice'} -> Option A
Quick Check:
