**Core Concept**
Tuberous sclerosis is a genetic disorder characterized by the growth of non-cancerous tumors in various parts of the body, including the skin, brain, kidneys, and other organs. The triad of tuberous sclerosis refers to the classic combination of symptoms that are commonly observed in patients with this condition.

**Why the Correct Answer is Right**
The triad of tuberous sclerosis consists of:

* **Adenoma sebaceum**, or facial angiofibromas, which are benign skin tumors that appear as red or pink spots on the face, particularly around the nose and cheeks.
* **Ash-leaf spots**, which are hypopigmented macules that appear as light-colored patches on the skin, often on the trunk or limbs.
* **Shagreen patches**, which are areas of thickened skin that appear as a leathery texture on the back or buttocks.

These symptoms are a result of the abnormal growth of cells and tissues due to mutations in the TSC1 or TSC2 genes.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is not part of the classic triad of tuberous sclerosis. However, it is worth noting that seizures are a common feature of the condition, often due to the presence of cortical tubers.

**Option B:** This option is not part of the classic triad of tuberous sclerosis. However, it is worth noting that renal angiomyolipomas are a type of tumor that can occur in patients with tuberous sclerosis.

**Option D:** This option is not part of the classic triad of tuberous sclerosis. However, it is worth noting that retinal hamartomas can occur in patients with tuberous sclerosis.

**Clinical Pearl / High-Yield Fact**
The triad of tuberous sclerosis is a classic combination of symptoms that should raise suspicion for this condition in patients with a family history or other risk factors. A detailed skin examination and imaging studies can help confirm the diagnosis.

**Correct Answer:** D.
