Hint:A catalytic converter is a control device for emissions. It converts toxic gases to less toxic pollutants by a redox reaction. It is a device that reduces toxic gases and pollutants in exhaust gas from an internal combustion engine.

Complete step by step answer:
A catalytic converter is a device that is used to reduce the emissions from an internal combustion engine.
The automobile generally produce three main emission that are nitrogen gas $\left( {{N_2}} \right)$ , carbon dioxide $\left( {C{O_2}} \right)$ and water vapour $\left( {{H_2}O} \right)$ .
This device reduces toxic gases and pollutants in exhaust gas from an internal combustion engine into less toxic pollutants by redox reactions.
These are most properly applied to exhaust systems in automobiles. These can also be used on generators, trucks, buses and on ships. They are also found on wood stoves to control emissions.
These convertors combine oxygen with carbon monoxide $\left( {CO} \right)$ and the unburned hydrocarbon $\left( {HC} \right)$ to produce $C{O_2}$ ( Carbon Dioxide) and ${H_2}O$ (water).
These catalytic converters are proved to be effective and reliable in the reduction of toxins.
As the catalytic converters are located externally in a vehicle and even include valuable and precious metals like platinum, palladium and rhodium, these are the main target for thieves.
Therefore the function of an automobile catalytic converter is to control the emissions of carbon monoxide $\left( {CO} \right)$ and hydrogen.
So, option (B) is correct.

Additional information: The catalytic converters are applied to exhaust systems in automobiles but they are also used on electrical generators, mining equipment, trucks, buses and on ships. They are also used on wood stoves to control emissions. This is done in response to government regulation or health and safety regulations.

Note:
The pieces of catalytic convertors and the heat produced by them can cause wildfires especially in the dry areas. This is the main drawback for the catalytic automobile converters.
