What is the benefit of code reuse in software development?

The benefit of code reuse in software development primarily lies in its ability to reduce software redundancy. When existing code components or libraries are reused, developers avoid rewriting the same code for different parts of an application or across different projects. This not only promotes consistency in functionality but also significantly decreases the likelihood of introducing bugs, as the reused code has already been tested and validated.

By leveraging established code, teams can focus on building new features and improving the quality of their applications, rather than reinventing the wheel. This efficiency ultimately leads to faster development cycles and a reduction in the overall amount of code that needs to be maintained. Thus, reducing redundancy contributes directly to making software development more efficient and maintainable over time.

While code reuse does not guarantee perfect security, as vulnerabilities can still exist within reused components, it is primarily recognized for its efficiency and the reduction of redundant efforts, making the correct answer about reducing software redundancy.
