What are three examples when chain-of-custody is paramount?

Blood alcohol level/drug tests
Invasion of privacy
Quality Assurance (QA)
Assault

The correct answer is: Blood alcohol level/drug tests

Chain-of-custody is the process of maintaining a document or evidence trail of a sample to ensure its integrity and accuracy. Blood alcohol level/drug tests require a strict chain-of-custody to ensure that the sample is not contaminated, tampered with, or mishandled in any way which could potentially impact the results. Invasions of privacy and assault, while also important, do not directly involve the handling and tracking of physical evidence and therefore do not require a strict chain-of-custody. Quality Assurance (QA) is an important part of any process, but it does not pertain to the handling of specific samples or evidence. Therefore, A is the most appropriate answer as it directly relates to the importance of maintaining chain-of-custody.
