   • AImmediately stop all testing and wait for the development team to fix the defect.
   • BInvestigate whether the defect is a regression caused by the current changes or an environment issue.

   A test manager is considering introducing test automation for a maintenance project. The system is a legacy application with a complex user interface and many manual test cases. The team has limited experience with automation. The test manager must decide whether to automate and, if so, which tests to automate first. What is the most appropriate approach?

   • AAvoid automation because the system is legacy and too complex to automate.
   • BStart by automating a small set of high-value, stable test cases, and gradually expand the automation suite.
   • CAutomate all existing manual test cases to maximize the return on investment.
   • DAutomate only the new test cases for the current release, leaving the existing ones manual.
