Solution

The correct option is E
Primary CO₂ fixation product - PGA

The primary CO₂fixation product in C₄plants is oxaloacetic acid, which is converted to malic acid or aspartic acid that is transported to the bundle sheath cells where the acid is decarboxylated and the CO₂thus released enters the Calvin cycle.
