When using classes in programming the concept of public and private members of a class (the data and the functions) is important. Which one of the following sentences best explains this concept? Select one: О а. Private members of a class are not meant to be accessed by code outside of the class but are visible to code belonging to a class. Only the public members should be used by code outside of the class itself. O b. Private members of a class can only be accessed by other private members of a class. Public members are accessible to all code. О с. Private members of a class should only be used by programmers with the correct authorisation. Public members of the class can be used by anyone. O d. Private members of a class should be used no differently than public members of a class. It is just used to make programming more complicated.
