CO2+C---> 2CO, is the answer

The right answer is A.

Named after the chemist Octave Leopold Boudouard (1872-1923), the balance of Boudouard corresponds to the reduction of carbon dioxide (of air) by solid carbon into gaseous carbon monoxide:


C (s) + CO2 (g) ==> 2 (CO) (g)


This is a redox reaction, more precisely disproportionation (carbon monoxide plays both the role of oxidizer and reducer).
