C and D could be both correct. However, in the code fragment we are creating object of class Ebook thus, it cannot be abstract. Thus, the correct answer is (D)

Selected Answer: D
The answer is letter D, answers A and B are clearly wrong, C would also be right, but what shows that it is wrong is the code fragment that calls the class directly. You cannot instantiate abstract classes directly as it was done in the code snippet, so the letter D is correct, implement the abstracted method.
