**Core Concept**
Bohn's nodules are a specific type of congenital anomaly characterized by small, cystic swellings that typically appear on the surface of the tongue in neonates. This phenomenon is associated with the presence of epithelial remnants, which fail to involute during fetal development.

**Why the Correct Answer is Right**
Bohn's nodules are formed due to the failure of the epithelial invagination in the tongue during embryonic development. As a result, small cystic structures are left behind, which can be palpated on the surface of the tongue in newborns. These nodules are usually benign and do not require any specific treatment, as they typically resolve on their own within the first few months of life.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because Bohn's nodules are specifically associated with the tongue, not other parts of the oral cavity or the entire body.

**Option B:** This option is incorrect because Bohn's nodules are not cysts associated with the soft palate, but rather with the tongue.

**Option C:** This option is incorrect because Bohn's nodules are not cysts of the gingiva in growing children, but rather a congenital anomaly present at birth.

**Option D:** This option is incorrect because Bohn's nodules are not warts on the tongue, but rather a benign, cystic swelling.

**Clinical Pearl / High-Yield Fact**
It's essential to recognize Bohn's nodules as a normal finding in newborns, as they can be mistaken for other oral lesions. A thorough clinical examination and knowledge of congenital anomalies are crucial for differentiating between benign and pathological conditions.

**✓ Correct Answer: A. Cystic swellings in neonates**
