B Correct answer
Explanation

Let there be x ml CO in the mixture. Hence, there will be (1000 – x) ml CO2 . The reaction of CO2 with red hot charcoal may be given as,CO2 (g) + C(s) → 2CO(g)from reaction we have, x = 400 ml Therefore volume of CO = 400 ml and hence the volume of CO2 = (1000 – 400 ) ml = 600 ml Hence, this is the correct option.
