**Core Concept**
The differentiation between antemortem and postmortem wounds in forensic pathology is crucial for determining the circumstances surrounding a death. Antemortem wounds occur before death, whereas postmortem wounds occur after death. Various characteristics can distinguish between these two types of wounds.

**Why the Correct Answer is Right**
To differentiate between antemortem and postmortem wounds, forensic pathologists examine several factors, including:
* Presence of bleeding or hemorrhage, which indicates that the person was alive when the wound occurred.
* Presence of soot or gunpowder residues, which can indicate a gunshot wound.
* Presence of livor mortis, which is the discoloration of the skin due to the pooling of blood after death.

**Why Each Wrong Option is Incorrect**
* **Option A:** is incorrect because the presence of bleeding or hemorrhage is a key indicator of antemortem wounds.
* **Option B:** is incorrect because soot or gunpowder residues can indicate a gunshot wound, which is typically an antemortem injury.
* **Option C:** is incorrect because livor mortis is a key indicator of postmortem changes, but it can also occur in antemortem wounds if the person was alive when the wound occurred.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that the presence of bleeding or hemorrhage is a strong indicator of antemortem wounds, whereas the absence of bleeding or the presence of livor mortis suggests a postmortem wound.

**Correct Answer:** D.
