B) It is logically impossible to demonstrate that a totally unreliable test is valid because validity refers to how well a test measures what it is supposed to measure, and reliability refers to the consistency of the test results. If a test is totally unreliable (i.e., it does not produce consistent results), it cannot provide a valid measure of what it is supposed to, since the inconsistency undermines the accuracy of what is being measured.
