Assuming that the following inheritance set is in force, which of the following classes are declared properly? (Choose two.)
Assuming that the following inheritance set is in force, which of the following classes are declared properly? (Choose two.)
Based on the provided inheritance set, 'D' classes can be declared because class 'D' inherits from 'B' and 'C', both of which ultimately inherit from 'A', which is valid. Similarly, class 'Class_4(C,B)' is properly declared because it inherits from both 'C' and 'B', and both 'C' and 'B' inherit from 'A'. Therefore, the proper declarations are 'Class_1(D): pass' and 'Class_4(C,B): pass'.
CD correct tested
C and D are corrects
