Which of the following best defines polymorphism in a programming context?

Polymorphism in a programming context refers to the ability to define multiple behaviors for the same interface. This concept allows methods to operate on objects of different classes as long as they share the same interface or base class. Through polymorphism, a single function can process different types of inputs, enabling more flexible and reusable code.

For instance, in object-oriented programming, a function that takes an interface type can work with any class that implements that interface. This allows different classes to define their own specific implementations of the same method while still being able to be treated uniformly by the client code that utilizes the interface.

This concept contrasts with shared interfaces, which highlight the commonality among various classes but do not encompass the idea of varying implementations. The exclusion of internal class details pertains more closely to encapsulation, which focuses on hiding implementation specifics rather than providing varied functionalities. Similarly, the relationship between subclasses and superclasses is related to inheritance rather than directly describing polymorphism, as polymorphism applies to the behavior exhibited through shared interfaces rather than just the structure of the class hierarchy.
