The answer is; 51% sucrose solution

The solution in the beaker has to be hypertonic to that in the dialysis bag for water to move from the bag into the beaker. This is guided by the principles of osmosis where water flows from the hypotonic solution to the hypertonic solution through a semipermeable membrane.
