**Core Concept**
Congenital adrenal hyperplasia (CAH) is a group of inherited disorders that affect the adrenal glands, leading to impaired production of cortisol and aldosterone. This results from mutations in genes encoding enzymes involved in the steroidogenesis pathway, particularly 21-hydroxylase, 11-hydroxylase, and 17-hydroxylase.

**Why the Correct Answer is Right**
The primary treatment for CAH involves hormone replacement therapy to correct the deficiency of cortisol and aldosterone. This typically includes glucocorticoids (e.g., hydrocortisone) and mineralocorticoids (e.g., fludrocortisone) to replace the deficient hormones. Additionally, some patients may require salt supplementation to prevent hyponatremia.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it is not a treatment for CAH. However, it is worth noting that some patients with CAH may require surgery to correct ambiguous genitalia or to remove an overgrown adrenal gland.

**Option B:** This option is incorrect because it is not a standard treatment for CAH. However, some patients with CAH may require medications to manage symptoms such as hypertension or hypokalemia.

**Option C:** This option is incorrect because it is not a treatment for CAH. However, it is worth noting that some patients with CAH may require medications to manage symptoms such as hypertension or hypokalemia.

**Option D:** This option is incorrect because it is not a treatment for CAH. However, it is worth noting that some patients with CAH may require medications to manage symptoms such as hypertension or hypokalemia.

**Clinical Pearl / High-Yield Fact**
It is essential to note that the treatment of CAH requires lifelong hormone replacement therapy and regular monitoring of electrolytes, blood pressure, and blood glucose levels. Patients with CAH should also be counseled on the importance of regular follow-up appointments and adherence to their treatment regimen.

**Correct Answer:** D.
