Ok guys.Here is your answer.I only typed it in VSSCODE and here it is:
https://drive.google.com/file/d/122fvfA91ZyKcsq7qlaBQXYcGH0x7e9Ja/view?usp=sharing
Why is the corract answer not Class(D,C): pass ??
D -> B -> A
C -> A
I do not understand why the correct answer is Class(C,D): pass
Can someone please explain?
Is that because in the inheritance
class B cannot be invoked before class C is invoked which is why it's Class(C,D): pass
C -> A
D -> B -> A
(class B invoked later on as it is initialized earlier than class C)
On multiple inheretance, the Parent cannot be declared before the child:

Can't be B, class A shouldn't be before class C, because class C is a subclass of class A.
The order left and right is important in python.
