Which process involves the transformation of cadaveric body fluids post-death?

The correct choice is putrefaction, which is the process involving the transformation of cadaveric body fluids after death. This occurs when bacteria and microorganisms begin to break down tissues and fluids, leading to the release of gases and various byproducts that contribute to the characteristic decomposition odors. Putrefaction is significant in forensics and mortuary science as it helps determine the time of death and the state of decomposition.

In contrast, autolysis refers to the self-digestion of tissues by enzymes contained within the cells, which starts shortly after death but does not specifically address the transformation of body fluids as a primary process. Fluid diffusion occurs naturally and is not a specific post-mortem process. Dehydration can happen to a body over time, but it is not a primary transformation of body fluids associated with the decomposition process as putrefaction is. Therefore, putrefaction is the most accurate term for the described transformation of cadaveric body fluids post-death.
