Which term is about using existing assets such as software, knowledge, code into new software?

• A. Extensibility
• B. Quadratic
• C. Logarithmic function
• D. Reusability

Answer: (D)

Using existing assets such as software, knowledge, or code in new software is reusability. It means designing and organizing components so they can be reused across projects—libraries, APIs, modules, patterns—so you don’t have to reinvent the wheel. This speeds development, reduces defects, and keeps consistency across systems. Extensibility is about adding new features to an existing product, not primarily reusing prior assets, and the other terms are unrelated in this context.
