Correct option is (d) 70-90 mmHg
Easiest explanation: The blood pressure within the glomerular capillaries is 70–90 mm of mercury. The blood flow through the capillary tuft is controlled by the state of contraction of the muscle of the arteriole leading to the tuft. The renal arteries carry blood at very high pressure from the aorta into the glomerular capillary tuft.
