A)...0 mls.....i think

coz..isotonic saline(0.9% Nacl)...wont diffuse to ICF....will diffuse across ECF only (plasma mostly,but can diffuse to interstitial fluid too)....

diffusion depends mainly on solute concentration not solvent....

thanks

Default A is right

just learnt this concept & thought to share like vencky rightly said

(1)Isotonic fluid stays only within the ECF compartment...eg
600mls of 0.9% Normal Saline -->150mls in Plasma,450mls in ISF,0mls in ICF

(2)Dextrose infusion will equillibrate within all compartments..eg
600mls Dextrose--->50mls in plasma,150mls ISF & 400mls in ICF

(3)Albumin infusion stays only within plasma compartment ..eg
600mls albumin--->600mls in plasma,0mls in ISF & ICF.......................
