**Core Concept**
The process of putrefaction after death is influenced by various factors, including the organ's location, blood supply, and bacterial load. Putrefaction is the breakdown of tissue due to the action of microorganisms, leading to the release of foul-smelling gases.

**Why the Correct Answer is Right**
The brain is the last organ to putrefy after death due to its unique anatomy and physiology. The brain is protected by the skull, which prevents bacteria from entering and colonizing the tissue. Additionally, the brain has a low bacterial load compared to other organs, such as the intestines, which are rich in bacteria. As a result, putrefaction in the brain occurs last, often taking several days to weeks after death.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the liver, although rich in blood supply, is not the last organ to putrefy. The liver's high metabolic rate and rich blood supply make it an ideal environment for bacterial growth and putrefaction.
**Option B:** This option is incorrect because the kidneys are not the last organs to putrefy. While the kidneys do have a rich blood supply, they are not as protected as the brain by the skull and are more susceptible to putrefaction.
**Option C:** This option is incorrect because the stomach is one of the first organs to putrefy due to its high bacterial load and acidic environment.

**Clinical Pearl / High-Yield Fact**
The order of putrefaction in organs is generally as follows: stomach, intestines, liver, kidneys, and finally the brain. This sequence is influenced by the organ's location, blood supply, and bacterial load.

**Correct Answer:** C.
