Answer 1

- Public:

When deriving a class from a public base class, public members of the base class become public members of the derived class and protected members of the base class become protected members of the derived class. A base class's private members are never accessible directly from a derived class, but can be accessed through calls to the public and protected members of the base class.

- Protected:

When deriving from a protected base class, public and protected members of the base class become protected members of the derived class.

- Private:

When deriving from a private base class, public and protected members of the base class become private members of the derived class.
