## **Core Concept**
Antemortem burns occur before death, while postmortem burns occur after death. The differentiation between antemortem and postmortem burns is crucial in forensic pathology to determine the sequence of events leading to death. The presence of certain characteristics in burn vesicles can help distinguish between antemortem and postmortem burns.

## **Why the Correct Answer is Right**
The correct answer can be deduced by analyzing the characteristics of antemortem and postmortem burn vesicles. Antemortem burn vesicles typically show signs of vital reaction, which include inflammation and tissue response.

## **Why Each Wrong Option is Incorrect**
- **Option A:** Tissue beneath vesicle is dry, hard & yellow - This description is more indicative of postmortem changes or eschar formation seen in deeper burns but not specifically a distinguishing feature of antemortem burns.
- **Option D:** Fluid in the vesicle is scanty - This is more characteristic of postmortem burns. In antemortem burns, the fluid in the vesicle is usually more abundant due to the inflammatory response.

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that antemortem burns typically show signs of vital reaction such as erythema (redness), and the presence of proteins and chlorides in the vesicle fluid due to the inflammatory response. The presence of erythema (option c) and increased protein & chlorides in vesicle fluid (option b) are indicative of antemortem burns.

## **Correct Answer:** B.
