**Core Concept**
Putrefaction is the process of decomposition of organic matter, particularly in the context of dead bodies. It's influenced by factors such as temperature, oxygen availability, and the presence of bacteria. The rate of putrefaction can be affected by various conditions, leading to its delay or acceleration.

**Why the Correct Answer is Right**
Putrefaction is typically delayed in cases where the body is:
* **Chilled or refrigerated**: Low temperatures inhibit the growth and activity of bacteria responsible for decomposition, thereby slowing down the process.
* **Preserved with formalin or other chemicals**: These substances act as antimicrobial agents, preventing bacterial growth and putrefaction.
* **Frozen**: The freezing process kills bacteria and prevents putrefaction.
* **Mummified**: Desiccation and lack of oxygen hinder bacterial growth, leading to delayed putrefaction.

**Clinical Pearl / High-Yield Fact**
In forensic pathology, the rate of putrefaction can be used to estimate the post-mortem interval (PMI), which is the time elapsed since death.
