20.
unlike small talk and most other anguages that support object oriented programming a c++ class can also be stand alone super class.
Option a correct.
21.
prolog is a essential typeless meaning that all code is effectively generic.
Option b correct.
26.
In c++ classes are defined as extension of c's record substructures-structs. This from of this structures(for the instance variable class) is called a class virtual table.
Option b correct.
27.
In c++ storage structure for the list (of dynamically bound methods of a class instance) is often called a called virtual method tables.
Option a correct.
31.
Subtyping is the primary purpose for the use of nested classes.
Option e correct.
