**Core Concept**
Throttling is a form of mechanical asphyxia caused by compression of the neck, leading to obstruction of the airway and/or blood vessels. This results in a combination of hypoxia, hypercapnia, and circulatory compromise.

**Why the Correct Answer is Right**
In throttling, the compression of the neck disrupts the normal anatomy of the airway and blood vessels. The compression of the trachea and larynx leads to obstruction of the airway, causing hypoxia and hypercapnia. The compression of the carotid arteries and jugular veins leads to circulatory compromise, further exacerbating the hypoxia. This combination of hypoxia and circulatory compromise ultimately leads to death.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is not a relevant cause of death in throttling.
**Option B:** While asphyxia is indeed a cause of death in throttling, the specific mechanism is more complex and involves both airway and circulatory obstruction.
**Option C:** This option is incorrect because it is not the primary cause of death in throttling.

**Clinical Pearl / High-Yield Fact**
In cases of throttling, the presence of petechial hemorrhages in the conjunctiva and eyelids (known as "pinpoint pupils") is a classic sign of asphyxial death.

**Correct Answer: C. Asphyxia due to compression of the airway and blood vessels.**
