The statement accurately describes the fundamental principle of the object-oriented (OO) approach. In this paradigm, a program is modeled as a collection of discrete, interacting "objects." These objects are instances of "classes," which serve as blueprints defining their structure (attributes) and behavior (methods). The power and structure of an OO program derive from the "interrelationships" between these classes and objects, such as inheritance, association, and composition, which allow them to communicate and work together to achieve the program's goals.

B. False: This is incorrect. The statement is a concise and accurate definition of the object-oriented paradigm. A program lacking interrelated objects and classes would not be considered object-oriented but would likely follow a different paradigm, such as procedural programming.

Section 2.1, "The Object Model": The authors state, "The object model is the collection of principles that form the foundation of object-oriented development... Stated simply, object-oriented development is a new way of thinking about software based on abstractions that exist in the real world. In this context, we view a system as a set of cooperating objects..." (p. 26). This supports the concept of a program consisting of interrelated (cooperating) objects.

Section "Objects": The course notes explain, "An object is a combination of data and procedures that work on the data... A key idea of object-oriented programming is to bring together data and the operations that use or modify that data." The lecture further discusses how systems are built by composing these objects, which inherently means they are interrelated.

Chapter 2, "How to Think in Terms of Objects": The text explains, "When you approach a problem in an OO fashion, you are really modeling a system... An object-oriented application is a collection of these objects sending messages to each other." (p. 23). This directly affirms that an OO program consists of a collection of interrelated (messaging/interacting) objects.
