Correct Answer: The appropriate technique to track problems with the requirements in a software development project is issue tracking. Issue tracking allows the business analyst to systematically monitor, manage, and resolve any issues or problems that arise during the project. This method ensures that issues are documented, prioritized, and addressed in a timely manner to prevent them from hindering project progress. Other methods such as baselining and RTM (Requirements Traceability Matrix) serve different purposes and are not specifically focused on tracking and managing problems.
