Solution

The correct option is C oxaloacetate
In C4 plants, initial fixation of CO2 or carboxylation occurs in mesophyll cells. The chloroplasts of mesophyll cells possess enzyme PEP carboxylase (or PEP case) for initial fixation of CO2 .The primary acceptor of CO2 is phosphoenol pyruvate or PEP. It combines with CO2 in the presence of PEP carboxylase (or PEP case) to form oxaloacetic acid or oxallocetate (OAA). So, the correct answer is 'oxaloacetate'.
