Kamma's answer is right. Here is the explanation:
First a brush of some C++ concepts:
1. In virtual inheritance, the most derived class calls the
virtual base class' c'tor/d'tor.
2. The class declared as 'friend class' can access the
private member functions of a class.
In A a; A' compiler tries to call A::A(), since its declared
as public its called. Now A::A() requires to call its parent
class's c'tor which although private but is able to be
called[1 above].
In C c; C::C() calls B::B()[2 above].
C being a non friend class can't access B::B() which is private.
