Solution

The correct option is C Assertion is correct but Reason is incorrect
Assertion:

Each molecule of NADPH and two ATP are required for fixation of one molecule of CO2.
Reason:
Three molecule of NADPH and two ATP are required for fixation for fixation of one molecule of CO2
Assertion is correct but Reason is incorrect.
Each molecule of ribulose-1,5-biphosphate fixes one molecule of carbon dioxide with the addition o water, thereby resulting in the formation of two molecules of 3-phosphoglyceric acid .The fixation and reduction of one molecule of CO2 requires three molecule of ATP and two of NADPh, coming from the photochemical reaction.
