❌ A. The CanBark interface doesn’t compile ❌ B. A class that implements HasVocalCords must override the makeSound() method ✅ C. A class that implements CanBark inherits both the makeSound() and bark() methods ❌ D. A class that implements CanBark only inherits the bark() method ❌ E. An interface cannot extend another interface ❌ F. All statements are false
Explanation: The code compiles without issue, so option A is wrong. Option B is incorrect, since an abstract class could implement HasVocalCords without the need to override the makeSound() method. Option C is correct; any class that implements CanBark automatically inherits its methods, as well as any inherited methods defined in the parent interface. Because option C is correct, it follows that option D is incorrect. Finally, an interface can extend multiple interfaces, so option E is incorrect.
