**Core Concept**
McCune-Albright syndrome is a rare genetic disorder characterized by **fibrous dysplasia** of bone, **café-au-lait** skin spots, and various **endocrine disorders**. It results from a mutation in the **GNAS** gene, leading to **constitutive activation** of **adenylate cyclase**. This mutation affects the **G-protein signaling pathway**.

**Why the Correct Answer is Right**
The correct answer is not provided, however, the syndrome typically presents with **precocious puberty**, **thyrotoxicosis**, and **growth hormone excess**. The **GNAS** mutation leads to **overproduction of cyclic AMP**, resulting in **hyperfunction** of affected endocrine glands.

**Why Each Wrong Option is Incorrect**
**Option A:** Not provided, however, typical features of McCune-Albright syndrome would be incorrect if they included **multiple hereditary exostoses** or other unrelated conditions.
**Option B:** Similarly, not provided, but incorrect if it mentioned **neurofibromatosis** or other distinct disorders.
**Option C:** Not applicable without the option text.
**Option D:** Also not applicable.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that McCune-Albright syndrome is a **sporadic** disorder, meaning it is not inherited in an autosomal dominant pattern like other **GNAS**-related conditions. The classic triad of **fibrous dysplasia**, **café-au-lait** macules, and **endocrine hyperfunction** should prompt consideration of this diagnosis.
