Final answer:
The design technique that helps reduce code duplication and benefits from using functions is code reuse. This technique allows developers to call the same code multiple times, simplifying maintenance and error management.
Therefore , the correct answer options is a)
Step-by-step explanation:
The design technique that helps to reduce the duplication of code within a program and is a benefit of using functions is code reuse. By abstracting common tasks into functions, developers can call the same code from multiple places in the program without rewriting it, which simplifies maintenance and reduces the likelihood of errors.
This contrasts with other concepts like divide and conquer, which is a strategy to solve complex problems by breaking them into smaller, more manageable ones; debugging, which is the process of finding and fixing issues in code; and facilitation of teamwork, which involves strategies to improve collaborative efforts among developers.
However, all these principles can intertwine, as modular functions (code reuse) can also facilitate teamwork by making it easier for multiple developers to understand and contribute to the codebase, while the divide and conquer approach can be part of both the design and implementation phases of software development.
