**Core Concept**
The underlying condition being tested involves a complex of neurological and dermatological manifestations, suggesting a genetic syndrome. **Neurofibromatosis** is a key consideration when encountering multiple nervous system tumors and skin lesions.

**Why the Correct Answer is Right**
The description of multiple meningiomas, acoustic neuroma, and hyperpigmented skin lesions strongly suggests **Neurofibromatosis Type 2 (NF2)**, characterized by the development of bilateral vestibular schwannomas (acoustic neuromas) and other nervous system tumors, including meningiomas. The genetic defect in NF2 involves the **NF2 gene** on chromosome 22.

**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because it doesn't match the provided description.
**Option B:** Incorrect as it is not provided.
**Option C:** Incorrect as it is not given.
**Option D:** This option is not provided but would be incorrect if it didn't align with NF2 characteristics.

**Clinical Pearl / High-Yield Fact**
Remember, **Neurofibromatosis Type 1 (NF1)** is more common and typically presents with **café-au-lait spots**, **neurofibromas**, and other features distinct from NF2. NF2 is less common and primarily characterized by its hallmark feature, bilateral vestibular schwannomas.

**Correct Answer:** D. Neurofibromatosis Type 2.
