**Core Concept**
The Spalding sign is a characteristic post-mortem finding associated with maceration, a process that occurs in the body after death, particularly in stillborn or fetal deaths. Maceration is a result of the enzymatic breakdown of tissues, leading to softening and discoloration of the skin and underlying structures.

**Why the Correct Answer is Right**
Maceration is characterized by the softening and disintegration of tissues, which can be observed in the skin and underlying organs. The Spalding sign, specifically, refers to the separation of the scalp from the underlying skull, resulting from the loss of cranial bone density and the breakdown of the scalp's attachment to the skull. This occurs due to the enzymatic action of proteolytic enzymes, such as cathepsins, which break down collagen and other proteins, leading to tissue softening and separation.

**Why Each Wrong Option is Incorrect**
**Option A:** Drowning does not typically result in maceration, as it involves the inhalation of water into the lungs, leading to pulmonary edema and congestion, rather than enzymatic tissue breakdown.

**Option B:** Mummification is a drying process that occurs in bodies exposed to dry air, resulting in the desiccation of tissues and skin, rather than maceration.

**Option D:** Starvation, while leading to tissue wasting and malnutrition, does not involve the same enzymatic breakdown of tissues as maceration.

**Clinical Pearl / High-Yield Fact**
The Spalding sign is a key indicator of maceration, and its presence can help forensic pathologists distinguish between stillbirth and neonatal death.

**✓ Correct Answer: C. Maceration**
