The last statement(Option D) might be assumed to be wrong by someone who is considering only a specific type of polymorphism - Override polymorphism.

Usually in an object oriented design approach, polymorphism is implemented by Overriding the member functions, but even same function names with different signatures qualify as polymorphic and this type of overload driven polymorphism is called Ad-Hoc Polymorphism.
