Testing only the invalid inputs (option B) does not guarantee that the system will provide an appropriate response to every invalid input since there can be other invalid inputs that were not tested. Testing only the valid inputs (option A) also does not test the response to invalid inputs. Therefore, testing both valid and invalid inputs in every possible combination (option C) is necessary to ensure that the system can handle all types of input and produce an appropriate response. Option D is incorrect as testing is necessary to guarantee the quality and reliability of the system.
