Correct option (a) Reductive carboxylation 

Explanation :

In dark phase or Calvin cycle, carbon dioxide is assimilated with the help of assimilatory power (ATP and NADPH2) to produce organic acid. The cycle involves redduction of carbon involving carboxylation, glycolytic reversal and regeneration of RuBP. C3 cycle is also known as reductive pentose pathway or photosynthetic Carbon Reduction (PCR)
