**Core Concept**
Hanging is a form of mechanical asphyxia caused by the compression of the neck structures, leading to obstruction of blood vessels and airway. The presence of neck ligature marks is a critical forensic finding that helps in determining the cause of death.

**Why the Correct Answer is Right**
Ligature marks are formed due to the constricting force exerted by the ligature around the neck, leading to the formation of a circumferential hematoma. This is typically seen in cases of hanging, where the ligature is tied around the neck, causing compression of the neck structures. The compression of the carotid arteries and jugular veins leads to cerebral hypoxia, resulting in loss of consciousness and ultimately death.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because ligature marks are not typically seen in cases of strangulation by manual compression of the neck.
**Option B:** This option is incorrect because ligature marks are not typically seen in cases of asphyxia due to drowning or inhalation of noxious gases.
**Option C:** This option is incorrect because ligature marks are not typically seen in cases of traumatic neck injuries, such as fractures or dislocations.

**Clinical Pearl / High-Yield Fact**
In cases of hanging, the presence of ligature marks on the neck is a classic forensic finding that, when combined with other evidence, can help in determining the cause of death. It is essential for forensic pathologists to carefully examine the neck for ligature marks and other signs of mechanical asphyxia.

**Correct Answer:** C.
