**Core Concept**
Post-mortem caloricity, also known as the "algor mortis" or "rigor mortis," is a phenomenon where the body temperature remains elevated after death. This occurs due to the residual metabolic activity of the body's cells and the continued conversion of ATP to heat.

**Why the Correct Answer is Right**
The correct answer is related to the concept of post-mortem caloricity, which is a result of the body's cellular metabolism. After death, cells continue to metabolize glucose, producing heat as a byproduct. This process is mediated by the enzyme pyruvate dehydrogenase, which is responsible for converting pyruvate into acetyl-CoA, a key step in the citric acid cycle. The continued activity of this enzyme and other cellular processes leads to the production of heat, resulting in an elevated body temperature.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not directly relate to the phenomenon of post-mortem caloricity. While it may be a related concept, it is not the correct answer.

**Option B:** This option is incorrect because it refers to a different medical concept. Post-mortem caloricity is not related to the "albicans" fungus, which is a type of yeast.

**Option C:** This option is incorrect because it refers to a different medical concept. Post-mortem caloricity is not related to the "calorie" unit of energy, which is a measurement of the energy content of food.

**Clinical Pearl / High-Yield Fact**
A classic exam trap is to confuse post-mortem caloricity with rigor mortis, which is a separate phenomenon. Rigor mortis is the stiffening of the muscles after death, whereas post-mortem caloricity refers to the elevated body temperature.

**Correct Answer: C. Dystropic calcification**
