## Core Concept
Tattooing around the entry wound is a forensic finding associated with gunshot injuries. It refers to the embedding of unburnt gunpowder particles into the skin around the wound of entry. This phenomenon occurs when a firearm is discharged at close range, but not directly in contact with the skin.

## Why the Correct Answer is Right
The correct answer, **C. Close range**, is right because tattooing or stippling happens when the gun is fired at a close range, but the muzzle is not pressed against the skin. In this scenario, the unburnt gunpowder particles are propelled into the skin, embedding themselves and creating the characteristic tattooing or stippling marks around the entry wound. This is a key piece of forensic evidence used to estimate the range of fire.

## Why Each Wrong Option is Incorrect
- **Option A:** This option is incorrect because tattooing is not typically seen with wounds caused by being at a distance where gunpowder particles do not reach the skin.
- **Option B:** This option might seem plausible but is incorrect because, in a contact gunshot wound, the muzzle is pressed against the skin, which usually results in an absence of tattooing due to the gunpowder being pushed into the wound track rather than embedding in the skin around it.
- **Option D:** This option is incorrect because exit wounds do not typically exhibit tattooing; rather, they may show signs of eversion of the skin edges and sometimes stippling or tattooing if there are still some gunpowder particles propelled back towards the direction of fire, but this is much less common.

## Clinical Pearl / High-Yield Fact
A key point to remember is that the presence of tattooing around a gunshot wound indicates that the firearm was discharged at close range but not in direct contact with the skin. This forensic clue helps investigators reconstruct the events surrounding a gunshot injury.

**Correct Answer: C. Close range.**
