Solution
The correct option is D carboxylation
Carboxylation is the fixation of CO2 into a stable organic intermediate. It is the most crucial step of the Calvin cycle where CO2 is utilized for the carboxylation of RuBP through the use of ATP and NADPH generated by the light reaction. This reaction is catalysed by enzyme RuBisCO which results in the formation of two molecules of 3-phosphoglyceric acid or PGA, which is the first stable product of photosynthesis. So the correct answer is 'carboxylation'.
