I think the correct answer from the choices listed above is option 3. The substance produced inside the leaf disks that caused them to float to the surface of the solution is oxygen. As oxygen is produced by photosynthesis, the disks will turn up on edge or even rise back up to the surface.

The process by which leaf disks float to the surface is as follows:

-Photosynthesis converts the carbon dioxide to oxygen

- Oxygen occupying the gas spaces in the leaf causes the leaf to rise.
