Cherry red color observed in forensic cases is due to which gas?

Explanation:
Cherry red coloration in forensic cases comes from carbon monoxide binding to hemoglobin to form carboxyhemoglobin. Carbon monoxide has a much higher affinity for hemoglobin than oxygen, so it displaces oxygen and the blood takes on a bright red hue. This distinct cherry-red appearance is a hallmark of CO poisoning and is not produced by the other gases listed.
