**Why the Correct Answer is Right**
The correct answer is not provided, however, in sarcoidosis, the granuloma is typically **non-caseating**, meaning it does not exhibit necrosis in the center, unlike caseating granulomas seen in tuberculosis. This distinction is crucial for diagnosis and is based on the **histopathological examination** of tissue samples.

**Option D:** Again, lacking the specific text, but it could be incorrect if it refers to a different pathological feature.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that **sarcoidosis** can affect virtually any organ, but it most commonly affects the **lungs** and **lymph nodes**. Recognizing **non-caseating granulomas** is crucial for diagnosing sarcoidosis.
