Solution

The correct option is C $3$ -PGA
In the Calvin cycle, carbon dioxide first combines with 5-C RuDP(Ribulose Diphosphate/bisphosphate) to form an unstable and unknown 6-C diphosphate compound. This compound then splits into two molecules of 3-PGA( phosphoglyceric acid).

So the correct answer is '3-PGA'.
