 A method is a programming concept that represents a function or a procedure that performs a specific task or action on an object. An object is a programming concept that represents an instance of a class or a data type that has properties and methods. A method would best describe the ability to jump for a boss object in game development because it is an action that the boss object can perform. Property, object, and attribute are not programming concepts that represent the ability to jump for a boss object in game development. Property is a programming concept that represents a characteristic or a feature of an object, such as color, size, or name. Object is a programming concept that represents an instance of a class or a data type that has properties and methods. Attribute is another term for property in some programming languages. References: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 4: Programming Concepts and Data Structures, page 143.
