Calvin cycle begins with fixation of CO2 into 3 C sugar by the process of carboxylation.
RUBISCO, present in the chloroplast stroma catalyzes carboxylation of ribulose -1, 5- biphosphate (RuBP) followed by immediate splitting of unstable product into 3-phosphoglyceric acid. Carboxylation is followed by a series of reduction reactions wherein 3 C compound 3-phosphoglyceric acid is reduced into 3 C compounds glyceraldehydes 3-phosphate (G3P); the reduction reactions are energized by ATP and NADPH serve as an electron donor. Three turns of Calvin cycle obtains 6 molecules of G3P, out of which one is used for glucose formation and rest are used in regeneration phase. The last phase of Calvin cycle, the regeneration phase ensures the continuous supply of RuBP for carboxylation and regenerates it using G3P.
Thus , the correct answer is 3-1-2...that is option (D)...

Explanation:
The Calvin cycle, also known as the C3 cycle, is the set of chemical reactions that take place in the chloroplasts of plants during photosynthesis. It is named after Melvin Calvin, who discovered these reactions. The Calvin cycle proceeds in three stages: reduction, regeneration, and carboxylation.
1. Reduction:
During the reduction stage, carbohydrate is formed at the expense of the photochemically made ATP and NADPH. In this stage, ATP and NADPH produced during the light-dependent reactions are used to convert carbon dioxide into a three-carbon sugar called glyceraldehyde-3-phosphate (G3P). This process requires the input of energy and reducing power from ATP and NADPH.
2. Regeneration:
During the regeneration stage, the carbon dioxide acceptor ribulose-1, 5-bisphosphate (RuBP) is formed. In this stage, some of the G3P molecules produced in the reduction stage are used to regenerate RuBP, which is essential for the continuation of the Calvin cycle. This regeneration process requires ATP generated from the light-dependent reactions.
3. Carboxylation:
During the carboxylation stage, carbon dioxide combines with rubulose-1, 5-bisphosphate (RuBP). In this stage, the enzyme Rubisco catalyzes the reaction between carbon dioxide and RuBP, resulting in the formation of an unstable six-carbon compound that quickly breaks down into two molecules of phosphoglycerate (PGA). This is the initial step in carbon fixation, where carbon from carbon dioxide is incorporated into an organic molecule.
Correct Sequence:
The correct sequence of the Calvin cycle is as follows:
1. Carboxylation (carbon dioxide combines with RuBP)
2. Reduction (carbohydrate is formed using ATP and NADPH)
3. Regeneration (RuBP is regenerated)
Therefore, the correct sequence is option D: 3-1-2
