The Calvin cycle produces only glucose from carbon-di-oxide and thus all the options are false.
Explanation
The Calvin cycle is the second stage of the photosynthesis chemical reaction.
It occurs in the absence of sunlight and after light reaction stage.
So from the light reaction stage oxygen gas is released and in the Calvin cycle the carbon-di-oxide absorbed by the stomata will react with other chemicals leading to formation of glucose.
As the Calvin cycle occurs in the absence of sunlight, the light energy cannot be absorbed by chloroplast during Calvin cycle.
Also the splitting of water into hydrogen and oxygen was completed in light reaction stage and in Calvin cycle only glucose is produced without water molecules.
Thus none of the options given occur during Calvin cycle.
The Calvin cycle only produces glucose from carbon-di-oxide captured by the stomata in the absence of sunlight and water molecules.
