Final answer:
The exact number of divisions in a typical crime lab can vary. Common divisions include drug analysis, DNA and biology, firearms and tool marks, toxicology, and trace evidence. Therefore, the standardized options in the question do not accurately represent the number of divisions; the correct option would be 'None of the above.'
Step-by-step explanation:
The typical crime lab is divided into several specialized divisions or departments; the exact number can vary depending on the size and function of the lab.
It is common to have divisions for drug analysis, DNA and biology, firearms and tool marks, toxicology, and trace evidence. However, because the question offers a limited number of options and none saying 'varies,' the answer is likely e. None of the above, implying the typical number is not represented in the options provided.
