C: Hyaline aeriosclerosis
Answer: C: Hyaline aeriosclerosis 
Explanation: Hyaline aeriolosclerosis is associated with benign hypeension. It is marked by homogeneous, pink hyaline thickening of the aeriolar walls, with loss of underlying structural detail, and luminal narrowing . The lesions stem from leakage of plasma components across injured endothelial cells, into vessel walls and increased ECM production by smooth muscle cells in response to chronic hemodynamic stress.
