Answer: B

Explanation:

Testing can demonstrate that there are defects in the software, by finding and reporting them. Testing cannot demonstrate that there are no defects, because it is impossible to test all possible scenarios and inputs. Testing cannot demonstrate that the software is correct, because correctness is a subjective and relative concept that depends on the expectations and requirements of the stakeholders. Testing cannot demonstrate that there are no hidden defects in the software, because hidden defects are those that are not detected by testing or other quality assurance activities.
