Which enzyme plays the role of a catalyst in CO2 fixation in C4 plants

1.	Which enzyme plays the role of a catalyst in CO2 fixation in C4 plants?(a) Carbonic mutase(b) Carbonic reductase(c) Carbonic anhydrase(d) Carbonic dehydrogenaseI had been asked this question during an interview.My question is based upon Chloroplast Function topic in portion Chloroplast Structure and Function of Cell Biology
Answer» The correct option is (c) Carbonic anhydrase Best explanation: Carbonic anhydrase is an enzyme, which plays the role of catalyst in the FIRST CO2 fixation STEP of C4 pathway. It helps the CO2 molecule to bind to the ACTIVE site of RuBisCO.
