More Dynamic and Flexible

CD is the correct Answer. In Enthuware Exam-Pool you will find the same question and the correct answer which is CD

B: More flexible and reusable code: Polymorphism makes code more flexible and reusable because it allows objects of different classes to be treated as if they are objects of the same class. This means that if you have a method that works with an object of a particular class, you can also use that method with objects of other classes that inherit from that class or implement the same interface. This can save a lot of time and effort because you don't have to write a separate method for each class.

C: Method overriding is runtime polymorphism. The process in which call to the overridden method is resolved at runtime, also known as dynamic method dispatch. D: Method overriding works together with inheritance to enable code reuse of existing classes without the need for re-compilation.

why cant C

The correct answer is BD, not much to explain. Polymorphism makes the code more efficient in the sense that an object accesses features of the parent or child class and it also makes the code more flexible.
