simple.. RBCs swell when placed in hypotonic solution. the only hypotonic solution in ans is
A. 75 mM of NaCl solution.

A, and my reason is

at point 0 in time we consider the solution to be 300mosml(isoosmolar), after that the volume of E doubles that means the solution is hypoosmolar 150 mosmol.

osmolarity= nr of particle X molal concentration of solution

that means molal concentration of solution is osmolarity/2=150/2=75

can anybody please explain the reduction in volume after the initial increase. i think it is due to rbc lysis... not sure...

I think you're right; some RBC will be destroyed by the internal pressure, so the MCV will be decreased.
