Correct answer is : B
The attributes with single underscores are considered as general attribute so can be directly accessed by obj.attributename.
So obj._a will give 1 . But _MyClass_a is undefined name here
Traceback (most recent call last):
File "C:/pythoneasy/test1.py", line 7, in <module>
print(obj._MyClass_a)
AttributeError: 'MyClass' object has no attribute '_MyClass_a'
