Answer:- [tex]Cl_2+2KBr\rightarrow 2KCl+Br_2[/tex]

Explanations:-  The first reaction is combustion reaction as the hydrocarbon is burned in presence of oxygen to give carbon dioxide and water.

Second reaction is the synthesis reaction as in general a synthesis reaction looks like:

[tex]A+B\rightarrow AB[/tex]

Third reaction is the decomposition reaction as it looks opposite of synthesis reaction.

[tex]AB\rightarrow A+B[/tex]

In general, a single displacement reaction looks like:

[tex]AB+C\rightarrow AC+B[/tex]

Fourth reaction is single replacement reaction as bromine is replaced by chlorine.

So, the correct choice is the last reaction, [tex]Cl_2+2KBr\rightarrow 2KCl+Br_2[/tex] .

Answer:

Cl2 + 2KBr ⟶ 2KCl + Br2
