How long does it take for rigor mortis to set in?
A
immediately after death
B
1-2 hours after death
C
4-6 hours after death
D
8-12 hours after death
Explanation: 

Detailed explanation-1: -Rigor mortis appears approximately 2 hours after death in the muscles of the face, progresses to the limbs over the next few hours, completing between 6 to 8 hours after death.

Detailed explanation-2: -For approximately the first 3 hours after death the body will be flaccid (soft) and warm. After about 3-8 hours is starts to stiffen, and from approximately 8-36 hours it will be stiff and cold. The body becomes stiff because of a range of chemical changes in the muscle fibres after death.

Detailed explanation-3: -Similarly, the rigor mortis, which is cadaveric rigidity, starts developing within 1 to 2 hours after death and takes around 12 hours after death for complete development and remains in the developed stage for further 12 hours and disappears in the next 12 hours generally.

Detailed explanation-4: -Algor mortis is applicable largely up to 24 h after death (Mathur and Agrawal, 2011). In this process, cadaver temperature decreases gradually by convection, radiation, conduction, and fluid evaporation (Myburgh, 2010) until it reaches an equilibrium with the environment often after 18–20 h (Fisher, 2004).

Detailed explanation-5: -Rigor mortis is one of the most well-known taphonomic alterations, and it is the process by which the body’s muscles stiffen, resulting in rigidity, as a result of a variety of chemical changes in the muscle structure. Stage I: Autolysis. Stage II: Bloat. Stage III: Active Decay. More items
