The picture shows an experimental set up for the process of osmosis. the potato has a cavity on top, as shown in the picture. some sugar solution is poured into the cavity and the potato is placed in a beaker of water. after some time, it is observed that there is a rise in the level of liquid in the cavity. this confirms that

The correct answer would be 

A) Water from the beaker has moved into the cavity.

Answer;

A) Water from the beaker has moved into the cavity.

Explanation;Osmosis is a physiological process which involves the movement of water molecules from a region where there are highly concentrated to a region where they are lowly concentrated through a semipermeable membrane.In the experiment water molecules moved from the beaker where they are highly concentrated to the cavity where they are lowly concentrated. Sugar solution is a hypertonic solution while the water in the beaker is hypotonic therefore water moves osmotically from the beaker through the potato to the cavity.
