Solution

The correct option is C Oxaloacetate
C4 plants:

In C4 plants, the primary $C O_{2}$ acceptor is phosphoenolpyruvate (PEP) which combines with $C O_{2}$ to form a 4- carbon stable product, that is, oxaloacetate (OAA).

C3 plants:

In C3 plants, the first stable product formed after the fixation of carbon dioxide is 3-phosphoglycerate.

Glycolysis:

Pyruvate is the product formed at the end of glycolysis during respiration and glyceraldehyde-3-phosphate is an intermediate product formed during glycolysis

Final answer: Oxaloacetate
