**Core Concept**
Spanish windlass is a method of execution involving the use of a rope or cord wrapped around the neck, tightened progressively to cause asphyxiation. It is classified under garrotting, a form of mechanical asphyxiation where neck compression leads to suffocation.

**Why the Correct Answer is Right**
The windlass mechanism involves a cord or rope being wound around the neck and pulled tightly, often with a lever or handle, to gradually constrict the airway. This action directly obstructs the trachea, leading to asphyxiation. Garrotting is characterized by mechanical compression of the neck, distinct from hanging or other methods. The term "windlass" refers to the tool used to tighten the rope, making it a variant of garrotting.

**Why Each Wrong Option is Incorrect**
Option A: Bansdola refers to a type of garrote, but it is not synonymous with windlass and is not a method of execution in the same context.
Option B: Mugging is a form of assault or robbery, not a method of execution.
Option D: Hanging involves suspension of the body by a rope, typically around the neck, and differs in mechanism and application from windlass-based garrotting.

**Clinical Pearl / High-Yield Fact**
In forensic medicine, garrotting is often identified by the presence of a tight, circular rope mark on the neck with signs of compression, and it is distinct from hanging due to the use of a windlass or lever to tighten the cord. Always differentiate between mechanical asphyxiation methods in post-mortem examinations.

✓ Correct Answer: C. Garrotting
