In which of the following is the rate of transpiration highest?

$A$ student performed an experiment on photosynthesis as follows: They took soda water in a glass tumbler and added chlorophyll to it. They placed the tumbler in sunlight,expecting that they had provided all the necessary components for photosynthesis (i.e.,$CO_2$,$H_2O$,chlorophyll,and light). What do you think will happen after a few hours of exposure to sunlight?
