(c) Oral ingestion of 200 ml of hypertonic NaCl
(d) Oral ingestion of 200 ml of hypertonic glucose solution

I would say a, because:
some of the water will equilibrate with the ICF, but will drop the osmolality. The resultant added vacular volume will increase urine production as well. NaCL will draw water out of cells and glucose will go into cells, but normally will not change osmolality. ADH will decrease plasma osmolality, but increases urine osmolality.

As substances are reabsorbed in the proximal convoluted tubules of the kidneys, they move from:
a) flitered fluid to epithelial cells, to interstitial fluid to peritubular capillaries
b) filtered fluid to interstitial fluid, to epithelial cells to pertubular capillaries
c) peritubular capillaries to interstitial fluid to epithelial cells to filtered fluid
d) vasa recta to epithelial cells to interstitial fluid, to filtered fluid
e) peritubular capillaries to epithelial cells, to interstitial fluid, to fitered fluid.
anyone>??? please answer it.
