The public interface of a class consists of the methods and variables that are visible and accessible to other objects interacting with the class. In this case, the only public method in the class is updateDimes. DIME_VALUE is also part of the public interface since it is declared as public static final. ObjectCounter and updateCounter are not part of the public interface since they are declared as private. Therefore, the correct answer is C, which includes both DIME_VALUE and updateDimes as part of the public interface.
