The incorrect statement is: The Calvin cycle can only occur in the presence of light.

The Calvin cycle is also known as the light-independent reactions. While it depends on the ATP and NADPH produced during the light-dependent reactions, it does not directly require light to occur. As long as there is a sufficient supply of ATP, NADPH, and carbon dioxide, the Calvin cycle can continue in the dark.

The other options are correct:

Option A: During the light-dependent reactions, light energy is converted into chemic...
