**Core Concept**
The patient's presentation of hypertension, virilization, and hypokalemia suggests a disorder of mineralocorticoid excess, which can lead to an overproduction of androgens.

**Why the Correct Answer is Right**
The correct diagnosis is Congenital Adrenal Hyperplasia (CAH) due to 21-hydroxylase deficiency. This enzyme deficiency leads to an accumulation of 17-hydroxyprogesterone, which is then converted to androgens, causing virilization. Additionally, the reduced production of aldosterone results in decreased potassium excretion, causing hypokalemia. The increased production of deoxycorticosterone (DOC) and 18-hydroxycorticosterone (18-OH-B) due to the enzyme deficiency leads to mineralocorticoid excess, causing hypertension.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is likely a distractor, but it does not provide a specific diagnosis that fits the patient's presentation.
**Option B:** This option may refer to a different condition, but it does not explain the patient's symptoms of virilization and hypokalemia.
**Option C:** This option may refer to a condition that causes hypertension, but it does not explain the patient's symptoms of virilization and hypokalemia.
**Option D:** This option is likely a distractor, but it does not provide a specific diagnosis that fits the patient's presentation.

**Clinical Pearl / High-Yield Fact**
CAH due to 21-hydroxylase deficiency is the most common form of CAH and accounts for approximately 90-95% of cases.

**Correct Answer:** C. Congenital Adrenal Hyperplasia (CAH) due to 21-hydroxylase deficiency.
