What information would be most relevant to determining the time of death?
Nuetrik [128]

Lividity can be defined as the typical bluish-purple discoloration of the skin after death. Rigor mortis can be defined as the postmortem state in which the muscles become stiff.

  • After death, the stomach contains identifiable ingested foods within two hours.

  • Rigor mortis is characterized by the stiffening of the body after death, which is caused by the absence of ATP in muscle tissues.

  • The most relevant information to determine the time of death is the presence of lividity, rigor mortis, and/or stomach contents (Option c).
