Which statement about the reactions of halogens with halide ions is correct?

Br2(aq)\text{Br}_2\text{(aq)}Br2​(aq) can oxidise Cl−(aq)\text{Cl}^-\text{(aq)}Cl−(aq).

Cl−(aq)\text{Cl}^-\text{(aq)}Cl−(aq) can reduce Br2(aq)\text{Br}_2\text{(aq)}Br2​(aq).

I−(aq)\text{I}^-\text{(aq)}I−(aq) can reduce Br2(aq)\text{Br}_2\text{(aq)}Br2​(aq).

Br2(aq)\text{Br}_2\text{(aq)}Br2​(aq) can reduce I−(aq)\text{I}^-\text{(aq)}I−(aq).
