To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) Class Diagram in the design model doesn't show real-world objects; rather it shows software classes only - This option is correct. In the design model, the class diagram represents the structure and relationships between software classes, not real-world objects.
Option B) Design Model illustrates the specifications for software classes and interfaces - This option is correct. The design model provides a high-level representation of the software system, including the specifications for software classes and interfaces.
Option C) Setters and getters should not be included in the Design Model - This option is incorrect. Setters and getters, also known as accessor and mutator methods, are commonly included in the design model to represent the behavior and properties of software classes.
Option D) Programming Language native libraries are shown in the Design Model - This option is incorrect. Design models typically do not include programming language native libraries. The design model focuses on representing the structure and behavior of the software system, not the specific libraries or frameworks used.
The correct answer is D. Programming Language native libraries are not shown in the Design Model because the design model is a higher-level representation of the software system, focusing on the structure and behavior of the system rather than specific implementation details.
