print(obj.a)

1. The program has an error because '__b' is private and can't be accessed outside of the class.

2. The program runs fine and will print 1.

3. The program has an error because 'a' is private and can't be accessed outside of the class.

4. The program has an error because you can't name a variable using '__b'.
