Answer
Substitutability allows an object to be replaced with its subtype without affecting the program's correctness.
Substitutability is a fundamental principle of polymorphism where objects of a superclass can be replaced with objects of a subclass without altering the desirable properties of a program. For instance, a method expecting a 'Shape' can accept 'Circle' or 'Square' objects without knowing their specifics, as long as they adhere to the 'Shape' interface or extend the 'Shape' class.
