**Core Concept**
Putrefaction is the process of breakdown of dead tissue by microorganisms, resulting in the production of foul-smelling compounds. The rate of putrefaction depends on various factors, including the type of tissue, the presence of oxygen, and the availability of nutrients.

**Why the Correct Answer is Right**
The liver is a rich source of glycogen, which serves as a substrate for bacterial growth. However, the liver's high concentration of lipids and its location in the abdominal cavity make it a less favorable environment for bacteria to grow, leading to delayed putrefaction. Additionally, the liver's relatively low water content and its rich blood supply contribute to its resistance to putrefaction.

**Why Each Wrong Option is Incorrect**
**Option A:** The stomach is a prime example of a tissue that undergoes rapid putrefaction due to its acidic environment and high bacterial load.
**Option B:** The intestines are also prone to rapid putrefaction due to their high bacterial content and rich supply of nutrients.
**Option C:** The muscles, particularly those in the abdominal wall, undergo putrefaction relatively quickly due to their high water content and rich blood supply.

**Clinical Pearl / High-Yield Fact**
It's essential to note that putrefaction rates can vary depending on environmental factors, such as temperature and oxygen availability. In cases of death in unusual environments, such as underwater or in extreme cold, putrefaction may be significantly delayed or even halted.

**Correct Answer: C. Muscles. Muscles.**
