The correct answer is option (A)

The tribromo octaoxide is a neutral molecule and does not contain any charge. The structure of molecules contain all oxygen atoms bonded with double bonds with bromine atoms. The molecule contains three bromine atoms and eight oxygen atoms.

Complete step by step answer:
Bromine combines with oxygen to give a variety of oxides. The tribromo octaoxide is the oxide of bromine that contain three bromine atoms and eight oxygen atoms. The structure of the oxide is as-

The two terminal bromine atoms bond with three oxygen atoms and a Br-Br bond. The central bromine atom forms a double bond with two oxygen atoms and a single bond with two bromine atoms. The molecule is neutral overall and does not contain any charge.
