What is wrong with this serializer code?

class CommentSerializer(serializers.Serializer):
    text = serializers.CharField()

serializer = CommentSerializer(data={'text': 123})
serializer.is_valid()

ARaises a TypeError during serializer creation

BValidation will fail because 'text' expects a string, but got an integer

CValidation will pass because integers are converted to strings automatically

DRaises a ValueError during is_valid() call

Step-by-Step Solution

Solution:

Step 1: Check field type requirements
CharField expects string input; integer input is invalid.
Step 2: Understand validation behavior
is_valid() will fail because 123 is not a string, so validation error occurs.
Final Answer:
Validation will fail because 'text' expects a string, but got an integer -> Option B
Quick Check:
CharField rejects non-string input [OK]

Quick Trick: CharField requires string input; integers cause validation error [OK]
