Which argument best supports the use of a cause-effect diagram in this situation?

   • AIt provides a structured way to explore all potential causes before deciding on solutions, reducing the risk of addressing symptoms rather than root causes.
   • BIt is the only tool that can be used for root cause analysis in test process improvement.
   • CIt eliminates the need for further data collection or investigation.
   • DIt guarantees that the root cause will be found quickly and with certainty.
