Solution

The primary benefit of Continuous Integration (CI) is that it significantly reduces integration issues by encouraging developers to frequently merge their code changes into a shared repository. This practice helps identify and address conflicts early in the development process, minimizing the risks associated with integration. By integrating code changes regularly, teams can maintain a consistent codebase, run automated tests, and detect errors quickly, leading to faster development cycles. CI promotes a culture of collaboration and feedback, allowing teams to improve code quality and delivery speed while reducing the time spent on integration-related issues. Why Other Options are Incorrect: A) It eliminates the need for testing: This is incorrect; CI includes automated testing as a crucial part of the process to catch errors early. B) It allows for immediate deployment to production environments: While CI facilitates rapid development, Continuous Delivery (CD) focuses on the deployment aspect. D) It focuses solely on improving the user interface: CI is a broader practice focused on integrating and testing code, not limited to UI improvements. E) It mandates that all code changes be reviewed by senior developers: CI does not require all changes to be reviewed by senior developers; instead, it emphasizes regular integration and testing among all team members.
