**Core Concept**
The last organ to be dissected during autopsy in asphyxial death is related to the pathophysiology of asphyxia, which often involves the brain's response to lack of oxygen. In asphyxial deaths, the brain undergoes significant changes, making its examination crucial for determining the cause of death.

**Why the Correct Answer is Right**
The last organ to be dissected is the brain because it is the most sensitive to hypoxia, and its examination is critical in asphyxial deaths. The brain's examination helps in determining the presence of anoxia, which can be a significant factor in asphyxial deaths. During an autopsy, the brain's examination is usually done last to prevent any contamination of the other organs with potential brain tissue.

**Why Each Wrong Option is Incorrect**
* **Option A:** This is incorrect because the last organ to be dissected in an autopsy is not the heart, which is typically examined early on in the autopsy process.
* **Option B:** This is incorrect because the liver is not the last organ to be dissected, and its examination is not as critical in asphyxial deaths as the brain's examination.
* **Option C:** This is incorrect because the lungs are typically examined early on in the autopsy process to determine the presence of any respiratory issues that may have led to the asphyxial death.

**Clinical Pearl / High-Yield Fact**
It is essential to note that in asphyxial deaths, the brain's examination can provide crucial information about the cause of death. The brain's examination should be done last to prevent any contamination of the other organs.

**Correct Answer: C. Lungs.
