Answer: This is a type of Synthesis reaction.

Explanation:

Synthesis reaction is a type of chemical reaction in which two or more substances combine to form a single substance.

Decomposition reactions are a type of chemical reactions in which a substance breaks down into two or more substances.

$AB\rightarrow A+B$

Combustion reaction is a type of chemical reaction in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide and water.

$Hydrocarbon+O_2\rightarrow H_2O+CO_2$

For the given reaction:

$2Na(s)+Cl_2(g)\rightarrow 2NaCl$

Here, 2 substances are combining together to form a single substance. Hence, it is considered as a synthesis reaction.
