form = MyForm()
form.is_valid()
print(form.errors)

CForm was not given any data to validate

DMyForm has no fields defined

Step-by-Step Solution

Solution:

Step 1: Check how the form instance is created
The form is created without passing any data, so it has no input to validate.
Step 2: Understand why errors are empty
Without data, form.is_valid() returns False but form.errors is empty because no fields were checked against input data.
Final Answer:
Form was not given any data to validate -> Option C
Quick Check:
No data means no validation errors = A [OK]

Quick Trick: Always pass data to form to test validation errors [OK]
