Explanation
Code reviews are a critical part of the development process, ensuring code quality, adherence to standards, and fostering team collaboration. They also help identify areas for optimization, though they do not eliminate the need for other testing methods. Understanding the principles and benefits of code reviews is essential for implementing effective DevOps and development practices.
- A. Correct.
Reviewing code helps ensure that coding standards and best practices are followed, reducing technical debt and improving maintainability.
