**Core Concept**
Adipocere formation is a process of post-mortem change where body fat is converted into a soap-like substance. This process typically occurs in moist environments and involves the action of bacteria that break down triglycerides into glycerol and fatty acids.

**Why the Correct Answer is Right**
Adipocere formation is promoted by the presence of specific bacteria such as Clostridium, which secrete lipases that break down triglycerides. In a moist environment, these bacteria thrive, facilitating the conversion of fatty acids into adipocere. The process is also influenced by factors such as temperature and pH, but the presence of specific bacteria is a key factor in promoting adipocere formation.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not specify a condition that promotes adipocere formation.
**Option B:** This option is incorrect as it is unrelated to adipocere formation.
**Option C:** This option is incorrect as it is a condition that actually inhibits adipocere formation, not promotes it.

**Clinical Pearl / High-Yield Fact**
Adipocere formation is often seen in bodies that have been submerged in water for an extended period, such as in drowning cases or in bodies recovered from rivers or lakes.

**Correct Answer: C. Putrefaction**
