A patient presenting with benign prostatic hyperplasia (BPH) and hypertension is prescribed a medication that selectively blocks alpha-1 adrenergic receptors. Which of the following effects is most likely due to this drug's mechanism of action?

✓ Correct Answer: Option C

Alpha-1 adrenergic receptor blockade causes relaxation of vascular smooth muscle, leading to peripheral vasodilation and reduced blood pressure, beneficial for hypertension. It also relaxes prostatic smooth muscle, improving BPH symptoms.
