A. class Class_3(A,C): pass This class declaration is proper based on the assumed inheritance set. It correctly inherits from classes A and C. B. class Class_4(C,B): pass This class declaration is also proper based on the assumed inheritance set. It correctly inherits from classes C and B. C. class Class_1(D): pass This class declaration is not proper based on the assumed inheritance set. It tries to inherit from class D, but D doesn't exist in the assumed inheritance set. D. class Class_2(A,B): pass This class declaration is not proper based on the assumed inheritance set. It tries to inherit from classes A and B, which is fine, but it doesn't cover all the necessary classes in the inheritance set (specifically, class C and its descendants). So, the proper class declarations are: A. class Class_3(A,C): pass B. class Class_4(C,B): pass upvoted 1 times Damon54 2 years, 5 months ago Sure ?!? upvoted 1 times ...

A. class Class_3(A,C): pass, it does not work because if the variable or method is not found in A it will not even be found in C as C inherits from A D. class Class_2(A,B): pass, the same thing doesn't work because if the variable or method is not found in A it won't even be found in B as B inherits from A upvoted 1 times
