Multiple Choice

Which of the following statements is true?

A) A class with multiple base classes can inherit constructors from any of its base classes.
B) If a class inherits constructors with the same signature from two or more base classes, then the derived class must define its own version of that constructor; otherwise, a compilation error occurs.
C) When a derived class is inheriting constructors from a base class and explicitly defines a constructor, if a default constructor is needed, the derived class must define a default constructor either by using = default to tell the compiler to generate the default constructor or by explicitly defining a constructor that can be called with no arguments.
D) All of the above.
