• Combustion

A new compound is formed by the combination of simpler reactants, such as nitrogen dioxide and oxygen combine (a component of smog) forming in the atmosphere. This is a ​ (a)  

• synthesis reaction

• decomposition reaction

• combustion reaction

Answer explanation

The question describes a process where simpler reactants, nitrogen dioxide and oxygen, combine to form a new compound. This is a characteristic of a synthesis reaction, where two or more simple substances combine to form a more complex substance. Therefore, the correct answer is 'synthesis reaction'.
