Answer:

The correct answer will be option- C.

Step-by-step explanation:

The filtration rate of the glomerulus is affected by the size of the arterioles: afferent and efferent. These arterioles are regulated through the hormones mainly prostaglandins, epinephrine, renin, angiotensin II and aldosterone.

The afferent arteriole vasoconstriction decreases the glomerular filtration rate (GFR) but in contrast, the vasoconstriction of efferent arteriole due to angiotensin II will increase the GFR because of the increase in glomerular capillary pressure.

Thus, option- C is the correct answer.
