Which of the following is NOT a tissue specimen collected for fatal cases?

Explanation:
In fatal-case investigations, tissue specimens refer to solid tissues collected to study cellular structure, disease processes, or to culture organisms—examples include liver tissue, brain tissue, and gastric tissue. These samples preserve tissue architecture for histology and related analyses. Urine, on the other hand, is a body fluid, not a tissue. It’s useful for toxicology or metabolic testing, but it does not provide a tissue sample to examine cells and tissue structure. Because the question asks for what is NOT a tissue specimen, urine is the correct choice.
