(b) Do acquire base class declaration of default arguments

(c) Do not link with the default arguments of base class

(d) Do link with the default argument but only of derived classes

I got this question in an interview.

I want to ask this question from Default Arguments topic in section Default Arguments vs Overloading, Upcasting and Downcasting of Object Oriented Programming

Answer 1

Right option is (a) Do not acquire base class declaration of default arguments

For explanation: The virtual function overrides do not acquire the base class declaration of default arguments. Even if a call to the virtual function is made, static type of the object decides the default arguments to be used.
