What can access a protected member of a class?

Only the same class members
Only friend functions
Derived classes, but not unrelated functions
Anyone

The correct answer is: Derived classes, but not unrelated functions

Protected members of a class can only be accessed by the same class members, such as constructors, member functions, and friend classes, as well as derived classes. This means that options A and B are partially incorrect since they do not include derived classes as an option. Option D is completely incorrect since anyone outside of the class or its derived classes cannot access protected members. Option C is the correct choice as it provides the most accurate and complete explanation of the access restrictions for protected members.
