What essential feature of an object-oriented programming language is demonstrated via late binding?

  1. Inheritance

  2. Encapsulation

  3. Polymorphism

  4. Abstraction

The correct answer is: Polymorphism

Choice A Inheritance is the ability for objects to acquire properties and methods from parent objects. Inheritance is not directly related to late binding. Choice B: Encapsulation is the concept of hiding the internal workings of an object and only exposing necessary information. While encapsulation is an important feature of object-oriented programming, it is not directly related to late binding. Choice D: Abstraction is the process of simplifying complex systems by only focusing on the essential aspects. While abstraction may be used when implementing late binding, it is not an essential feature of an object-oriented language. Late binding, or dynamic binding, is a programming technique where the code to be executed is determined at runtime rather than at compile time. This allows for more flexibility and extensibility in an object-oriented program. Late binding is an essential feature of polymorphism, as it allows different objects to respond differently
