   A test team used a fault seeding tool to insert 60 faults into a system. The tool automatically tracks detection. After running the test suite, the tool reported that 45 seeded faults were detected. The team also found 18 real defects. However, the team suspects that the tool inserted faults that are easier to detect than typical real defects. What is the most appropriate action?

   • ADiscard the estimate and use a different testing technique, as fault seeding is not valid in this case.
   • BAdjust the estimate upward to account for the likely lower detection rate of real defects compared to the seeded faults.
   • CIncrease the number of seeded faults to improve the accuracy of the estimate.
   • DUse the estimate of 24 remaining real defects as is, since the tool is automated and reliable.
