The third option is correct: the glucose would be found because it would reach an equilibrium.
Explanation: dialysis tubing is permeable to small molecules like glucose, so glucose diffuses out down its concentration gradient until the concentrations inside and outside balance. Thus a glucose test of the solution inside the tubing would be positive (though at a lower concentration than originally). The first two choices are incorrect because glucose was inside to begin with and it does not all instantly leave the tubing.
