**Core Concept**
Carbolic acid poisoning, also known as phenol poisoning, is a toxic condition caused by the ingestion or absorption of phenol. The **pathophysiology** of carbolic acid poisoning involves the disruption of cellular membranes and the denaturation of proteins.

**Why the Correct Answer is Right**
The correct answer is related to the specific effects of carbolic acid on the body. Carbolic acid is a corrosive substance that can cause severe **chemical burns** and **necrosis** of tissues. Upon ingestion, it can lead to **coagulative necrosis** of the gastrointestinal tract and other organs.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not accurately describe the characteristic postmortem finding of carbolic acid poisoning.
**Option B:** This option is also incorrect as it is not a specific finding associated with carbolic acid poisoning.
**Option C:** Similarly, this option does not accurately represent the postmortem findings of carbolic acid poisoning.
**Option D:** This option is incorrect because it is not a characteristic postmortem finding of carbolic acid poisoning.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that carbolic acid poisoning can cause **severe chemical burns** and **necrosis** of tissues, leading to distinct postmortem findings.

**Correct Answer:** D. White necrotic lesions in the gastrointestinal tract and kidney.
