Which BAC tests require the person to be deceased for the procedure?

The correct choice indicates that both a brain biopsy and a liver probe necessitate the subject to be deceased for the procedure to be performed.

To understand this, it’s important to consider the nature of these procedures and the context in which they are used. A brain biopsy involves removing a sample of brain tissue for examination, typically only performed on deceased individuals to assess conditions like disease or injury. Similarly, a liver probe is executed to analyze liver tissues or conditions, usually in cases of autopsy or post-mortem examinations. Both procedures require intact biological samples that can only be acquired when the person is no longer living.

In contrast, the other tests mentioned, like urine tests, blood tests, and breath tests, do not require the person to be deceased and can be conducted on living individuals to determine substances in the body or blood alcohol concentration. Understanding the specific requirements and applications of these tests is crucial for interpreting forensic and clinical scenarios correctly.
