Which ionic equation shows the formation of the cream precipitate in the test for halide ions?

[1]
A

Ag++Cl−→AgCl\text{Ag}^+ + \text{Cl}^- \rightarrow \text{AgCl}Ag++Cl−→AgCl

B

Ag++I−→AgI\text{Ag}^+ + \text{I}^- \rightarrow \text{AgI}Ag++I−→AgI

C

2Ag++Br−→Ag2Br2\text{Ag}^+ + \text{Br}^- \rightarrow \text{Ag}_2\text{Br}2Ag++Br−→Ag2​Br

D

Ag++Br−→AgBr\text{Ag}^+ + \text{Br}^- \rightarrow \text{AgBr}Ag++Br−→AgBr
