Option (a)- is correct because The equilibrium of hydrostatic and colloid osmotic pressure within the glomerular membrane is known as the Glomerular filtration rate. Autoregulation maintains renal blood flow between mean arterial blood pressures of 80 and 180 mmHg, so the Glomerular filtrate rate remains constant. The Net filtration pressure gradient in the barrier is 10mmHg.

Option (b)- is incorrect because the hydrostatic force in Bowman’s capsule will be 18 mmHg which conflicts with filtration.

Option (c)- is incorrect because the glomerular hydrostatic force will be 60 mmHg which allows filtration. 

Option (d)-  is incorrect because the colloid osmotic force of glomerular plasma proteins will be 32 mmHG which conflicts with filtration.
