The first question asks about the derivations of classes. The arrows
in the diagram indicate "derives from". That is, if class B has an
arrow to class A that means that class B derives from class A. With
that in mind we can answer each of the given questions:

i) A is a derived class of B and B is a derived class of C.

This is false. The arrows go from C to B and B to A, not the other
way around.

ii) C is a derived class of B and B is a derived class of A.

This is tue. The arrows are heading in the correct direction.

iii) A and B are both derived classes of C.

False. Instead C derives from B (and A).

iv) B and C are both derived from A.

True. B derives ...
