Some amendments need to be done for the options.

What is flue gas? 
Sandeep Das said: (May 6, 2016)  
Can anyone explain the solution? 
Biren Desai said: (Jul 8, 2016)  
Answer is wrong right answer is 3/11 co2 and 3/7 Co.

Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator. Quite often, the flue gas refers to the combustion exhaust gas produced at power plants.

Mass of carbon = 12 Mass of O2 = 32. CO2(12+32) =44 + CO (12+16) = 28. Mass of carbon present 44/12 CO2 + 28/12 CO. 11/3 CO2 + 7/3 CO. 
Biplab said: (Dec 28, 2016)  
CO2 + CO = C. C = 12, O2 = 32, O = 16, CO2 = 32 + 12 = 44, CO = 12 + 16 = 28, CO2 + CO = C, 44 kg + 28 kg =12 kg, 44/12 kg + 28/12 =1 kg carbon, 11/3 kg + 7/3 kg = 1 kg carbon.

We know that one kg of carbon produced 11/3 kg of CO2 and 7/3 kg of CO. So per kg of this gaseous, carbon will be produced 3/11 kg of CO2 and 3/7 kg of CO. So, according to me, no any answer is correct in above mention option. 
Anurup said: (Jun 15, 2017)  
It think 3/11CO2 + 3/7CO. 
Chahat Sharma said: (Jun 17, 2017)  
Yes, you are correct @Sarfaraz. 
Mehul said: (Dec 4, 2017)  
Right answer is 3/11CO2 + 3/7CO. 
J.T.R said: (Dec 9, 2017)  
No, the correct answer is 3/11 co2+ 3/7 co.

@Biplab. CO2 + CO = C is not balanced. I think Balanced equation is CO2+2CO=3C+2O2.

The mass of carbon, contained in 1 kg of flue or exhaust gases, may be calculated from the mass of carbon dioxide and carbon monoxide present in them. We know that 1 kg of carbon produces 11/3 kg of carbon dioxide. Hence 1 kg of carbon dioxide will contain 3/11 kg of carbon. Also, 1 kg of carbon produces 7/3 kg of carbon monoxide, hence 1 kg of carbon monoxide will contain 3/7 kg of carbon. Mass of carbon per kg of flue gas is given by: 3/11CO2 + 3/7CO. 
Tejaa said: (Oct 21, 2018)  
Yes, right @Syed Sameer. 
Kapil said: (Aug 12, 2019)  
I think the answer would be 3/11CO2 + 3/7CO.

We know that 1 kg of carbon produces 11 / 3 kg of carbon dioxide. Hence 1 kg of carbon dioxide will contain 3 / 11 kg of carbon. Also, 1 kg of carbon produces 7/3 kg of carbon monoxide, hence 1 kg of carbon monoxide will contain 3/7 kg of carbon. Mass of carbon per kg of flue gas is given by: 3/11 CO2+ 3/7 CO.
