What does the term polymorphism literally mean?

• A. Code reuse
• B. Static typing
• C. Many forms
• D. Child-parent relationship

Answer: (C)

Polymorphism literally means many forms—the word comes from poly (many) and morph (form). In programming this captures the idea that the same operation or interface can work with objects of different types, each providing its own form of the behavior. For example, a single method name like draw can produce a circle, square, or triangle, depending on the object’s class. This shows up as runtime polymorphism when a base type reference calls a method that runs the derived class’s version, and as compile-time polymorphism when the same method name is overloaded with different parameters. The other notions—code reuse, static typing, or a strict child–parent relationship—don’t express the literal meaning of the term, even though they often appear alongside polymorphism in OO design.
