D Correct answer
Explanation

Blood vessels leading into Bowman's capsule are called afferent arterioles and discharge blood into an efferent arteriole. Because the calibre of the efferent arteriole is smaller than that of the afferent arteriole, a resistance to blood flow out of the golmeruli is developed. As a result, a golmerular hydrostatic pressure builds up in the glomerulus.
