The correct answer is C
Hyperplastic arteriolosclerosis is commonly associated with malignant HTN. With ongoing injury, the vascular walls hypertrophy due to hyperplasia of SMCs and sometimes this occurs along with necrosis of the vessel wall. There is a characterisitic “onion-skin” appearance of the vessel wall.
Hyaline Arteriolosclerosis: The lesions are characterized by glassy thickening of arterial and arteriolar walls. Hyaline arteriolosclerosis is seen in elderly patients, with or without hypertension or diabetes, and in patients with long-standing diabetes but the lesions are most common and most severe in hypertensive patients.
