Answer:
The "is-a" statement is an accurate description of the concept of polymorphism in Object Oriented Programming. Polymorphism help with abstraction in Object Oriented Programming.
Step-by-step explanation:
Polymorphism enables you to “program in the general” rather than “program in the specific.” In particular, polymorphism enables you to write programs that process objects that share the same superclass (either directly or indirectly) as if they’re all objects of the superclass; this can simplify programming.
With polymorphism, we can design and implement systems that are easily extensible—new classes can be added with little or no modification to the general portions of the program, as long as the new classes are part of the inheritance hierarchy that the program processes generically.
