Example of ______ evidence: Blood Type- can be A, B, AB, O.

• A. Physical
• B. Class
• C. Biological
• D. Trace

Answer: (B)

Blood type is an example of class evidence. The main idea is distinguishing class evidence from individual evidence. Blood type can be A, B, AB, or O, and many people share each type. That means the finding points to a group of people who could have produced the sample, not a single, unique source. It can help narrow down suspects or exclude someone, but it cannot identify one person on its own. While blood itself is a biological material, the way this trait is used in evidence classification is as class evidence because it does not uniquely source to one individual.
