B Correct answer
Explanation

Yes, it is correct. Calvin and his co-workers worked out the whole pathway and showed that the pathway operated in a cyclic manner; the RuBP (Ribulose bisphosphate) was regenerated. The Calvin cycle can be described under three stages: carboxylation, reduction and regeneration.
