Which term is a simplified representation of something more complex, helping manage complexity by hiding details?

• A. Debugging
• B. Function
• C. Boolean
• D. Abstraction

Answer: (D)

Abstraction is a way to manage complexity by creating a simple representation that hides the details of how something works. In code, you interact with high-level ideas or interfaces without needing to know the inner steps it takes to perform a task. This lets you focus on what you want to accomplish rather than the low-level implementation. For example, using a prebuilt function or block lets you achieve a result without understanding every instruction that runs behind the scenes. The other terms describe related ideas: a function is a reusable block of code, debugging is about finding and fixing errors, and a boolean is just a true/false value. Abstraction best captures the idea of presenting a simplified view that hides complexity while still enabling work to be done.
