Hint: One of the constituents of syngas is highly combustible and colorless diatomic gas. The other constituent gas has a bond order of 3 between its atoms and also is colorless. Syngas is used in synthesis of some compounds.

- Syngas is also called synthetic gas.
- Syngas is a type of a fuel gas which is a mixture of carbon monoxide and hydrogen gas. Carbon dioxide is present in syngas in trace amounts.
- It is given name-syngas because it is used as an intermediate in the production of synthetic natural gas (SNG) and in production of ammonia and methanol.
-The mixture of $C{O_2} + {H_2}$ is called Carbogen. It is also called Meduna’s mixture. So, option (A) is not correct.
- The mixture of $CO + C{O_2}$ and $CO + {O_2}$ does not have any specific name given. So, option (C) and (D) are also not correct.
- Thus the mixture of $CO + {H_2}$ is called syngas.

So, the correct answer is “Option (B) $CO + {H_2}$”.
