Which equation represents chlorine displacing bromide ions?

[1]
A

Cl2+2Br−→2Cl−+Br2\mathrm{Cl_2+2Br^-\rightarrow2Cl^-+Br_2}Cl2​+2Br−→2Cl−+Br2​

B

Br2+2Cl−→2Br−+Cl2\mathrm{Br_2+2Cl^-\rightarrow2Br^-+Cl_2}Br2​+2Cl−→2Br−+Cl2​

C

Cl−+Br−→ClBr\mathrm{Cl^-+Br^-\rightarrow ClBr}Cl−+Br−→ClBr

D

Cl2+Br2→2ClBr\mathrm{Cl_2+Br_2\rightarrow2ClBr}Cl2​+Br2​→2ClBr
