The correct formula for cobalt(III)bromide is CoBr3, which represents one cobalt ion with a +3 charge and three bromide ions with a -1 charge each. Option A (CO₃Br) and Option C (CO₃Br₂) both do not make sense because they have a carbonate ion (CO₃) instead of cobalt. Option D (CO₂Br3) also does not make sense because there is no such thing as a CO₂ ion.
