Answer Key / Explanation : (c) -

(c)

Assimilation and reduction of carbon dioxide takes place during Calvin cycle. This cycle takes in only one carbon (as ) at a time so it takes six turns to produce a hexose or glucose molecule (6 carbon). In Calvin cycle, for formation of one mole of hexose sugar (glucose) 18 ATP and 12  are used. The assimilatory power (  and ATP) are generated in light reaction of photosynrthesis.
