The dependent variable in the osmosis practical is the change of mass of the potato (option 3). This is because the change in mass of the potato will be impacted by the different solutions it is placed in (option 2). The weighing and measuring of the potato before the test (option 1) is important for establishing a starting point, but it is not the dependent variable being measured or affected by the experiment.
