Br3 seems kinda strange.

will wait for anwser

 

[Duffs]

I am going with Br3

 

[Randy Holmes-Farley]

And the answer is...A. Br₃

There is no such chemical as Br₃, as folks noted.

The others result from the reaction of ozone with bromide (Br^-) and Iodide (I^-) in seawater. They can be toxic but these highly oxidized species can be catalytically broken down on GAC, so that's one of the reasons to treat the water after ozonation.
