In the experiment of demonstration of osmosis in a living system using the Potato Osmoscope where in a peeled potato a cavity is made and filled with the concentrated sugar and then placed into a beaker, also a mark is made on the same to identify the initial level.

In this experiment, it was observed that the sugar solution in the cavity of the potato becomes colored and the level rises which proves the entry of water into the sugar solution via the potato tissues which act as the selectively permeable membrane.

Hence, the correct answer is option 1.
