**Core Concept**
Pheochromocytoma is a rare tumor of the adrenal gland that produces excess catecholamines, leading to hypertension and other symptoms. Management involves controlling blood pressure and preparing the patient for surgery. **Alpha-blockers** and **beta-blockers** are used to control blood pressure, while other medications may be used to manage symptoms or prepare the patient for surgery.

**Why the Correct Answer is Right**
Since the correct answer is not provided, let's discuss the typical drugs used in pheochromocytoma. **Phenoxybenzamine** is an **alpha-blocker** used to control blood pressure by blocking alpha-adrenergic receptors. **Propranolol** is a **beta-blocker** used to control tachycardia and other symptoms. **Mettyrosine** is used to decrease catecholamine production.

**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific drug, we cannot determine why it is incorrect.
**Option B:** Similarly, without the specific drug, we cannot assess its incorrectness.
**Option C:** Same as above, lacking the specific drug to evaluate.
**Option D:** This option's incorrectness also cannot be determined without the specific drug.

**Clinical Pearl / High-Yield Fact**
A crucial point in managing pheochromocytoma is to always start with **alpha-blockade** before considering **beta-blockade**, as unopposed alpha-adrenergic receptor stimulation can worsen hypertension.
