Solution

The correct option is B $C O_{2}$
In Moll's half leaf experiment a destarched plant is used.Half part of one of the leaves from the plant is inserted into a corked bottle containing either KOH solution or KOH palletes. The plant is then placed in sunlight for a few hours. The leaf is then tested for starch with iodine solution. Part of the leaf that was inserted in the bottle does not turn blue or test positive for starch. This is because $C O_{2}$ present in the bottle was aborbed by KOH and the bottle was corked to prevent any entry of air.Proving that $C O_{2}$ is essential for photosynthesis.
So, the correct answer is $CO_2$

A student sets up an experiment on photosynthesis as follows: He takes soda water in a glass tumbler and add chlorophyll extracts into the contents and keeps the tumbler exposed to sunlight hoping that he has provided necessary ingredients for photosynthesis to proceed (viz., CO2, H2O, chlorophyll and light). What do you think what will happen after, say, a few hours of exposure of light?
