Solution

The correct option is B Reduction
In the second stage of the C3 cycle i.e., reduction, NADPH & ATP utilize their stored energy for the conversion of 3-PGA molecules that were created by carbon fixation into G3P. From the cycle, a G3P molecule gets involved in the synthesis of glucose. Because glucose has 6 carbon atoms, it takes six full turns of the Calvin cycle to make one glucose molecule.
So the correct option is 'reduction'
