What is a major benefit of using modular design in software development?

• A. It increases code redundancy
• B. It facilitates easier testing and maintenance
• C. It simplifies user interface design
• D. It eliminates the need for documentation

Answer: (B)

Using modular design in software development significantly enhances the ease of testing and maintenance. This approach involves breaking down a software system into smaller, manageable modules that can be developed, tested, and updated independently. Each module encapsulates a specific functionality, which leads to several advantages. First, during the testing phase, individual modules can be tested separately, allowing developers to identify and isolate issues more efficiently. This targeted testing reduces the complexity and time required to troubleshoot problems, as each module can be validated on its own before integrating it with other parts of the system. Second, in terms of maintenance, when changes are necessary—whether to add new features, fix bugs, or improve performance—modular design allows developers to update only the affected modules without needing to rework the entire system. This modular approach minimizes the risk of introducing new errors into unrelated areas of the software and allows for quicker updates and iterations. Additionally, the structure provided by modular design promotes cleaner code organization and enhances collaboration among software development teams, as different team members can work on separate modules simultaneously without conflict. In contrast, other options do not accurately capture the benefits of modular design. Increasing code redundancy works against efficiency and maintainability, simplifying user interface design is not directly tied to modular principles, and eliminating
