3rd to last quick 10 pts for u biology experts.?

what is the mechanism for the filtration of blood within the nephron?
a. the active transport of Na+ and glucose, followed by osmosis
b. both active and passive secretion of ions, toxins, and NH3 into the tubule
c. high hydrostatic pressure of blood forcing water and small molecules out of the capillary
d. the high osmolarity of the medulla that was created by active and passive transport of salt from the tubule and passive diffusion of urea from the collecting duct
e. a lower osmotic pressure in Bowman's capsule compared to the osmotic pressure in the glomerulus
