## **Core Concept**
The question pertains to the process of putrefaction, which is the breakdown of tissues after death due to the actions of bacteria and enzymes. Different tissues have varying rates of putrefaction based on their composition, bacterial load, and environmental conditions.

## **Why the Correct Answer is Right**
Bone tissue putrefies late compared to soft tissues like muscles, skin, and intestines. This is because bone has a dense structure with less moisture and a lower bacterial load, making it more resistant to early putrefaction. The process of putrefaction in bones is slower and often requires more time and specific conditions.

## **Why Each Wrong Option is Incorrect**
- **Option A:** Liver putrefaction occurs relatively early due to its high bacterial load and moisture content, making it a site of early putrefaction.
- **Option B:** Intestine putrefaction also occurs early for similar reasons as the liver; it has a high bacterial load which contributes to early breakdown.
- **Option C:** Muscle tissue, being rich in moisture and having a moderate bacterial load, putrefies earlier than bone tissue.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that putrefaction rates can vary significantly based on environmental conditions such as temperature, presence of oxygen, and the initial bacterial load of the tissue. However, in general, bone is noted for putrefying late compared to soft tissues.

## **Correct Answer:** D. Bone.
