A superclass' members are accessible anywhere that the program has a reference to an object of that superclass or to an object of one of its subclasses if the members have what access modifier?a.publicb.privatec.protected

The members of a superclass are accessible anywhere that the program has a reference to an object of that superclass or to an object of one of its subclasses if the members have a 'public' or 'protected' access modifier.

Here's why:

a. Public: The members (fields, methods, etc.) declared as public in a superclass are accessible anywhere in the program.

b. Private: The members declared as private in a superclass are not accessible directly from its subclasses or anywhere outside the class. They are only accessible within the class they are declared.

c. Protected: The members declared as protected in a superclass are accessible within the same package and also in its subclasses irrespective of the package they are declared in.

So, the correct answers are 'public' and 'protected'.
