Which postmortem parameter reaches a maximum at 12 hours and is gone within 36 to 48 hours?1. rigor mortis2. cloudiness of the eyes3. livor mortis4. algor mortis

The cloudiness of the eyes increases to a maximum and then decreases. This is because initially, after death, all the muscles relax, dilating the pupil. Some time later, rigor mortis sets in, contracting the pupil. Thus, the cloudiness fades.
