(B) The structure of the peroxoborate ion $[B_2(O_2)_2(OH)_4]^{2-}$ consists of two boron atoms linked by two peroxo bridges. Each boron atom is bonded to two hydroxyl groups and two oxygen atoms of the peroxo bridges. By observing the structure,we can identify three distinct types of $O-B-O$ bond angles: $1$. The angle between the two hydroxyl oxygen atoms $(HO-B-OH)$. $2$. The angle between a hydroxyl oxygen and a peroxo oxygen $(HO-B-O)$. $3$. The angle between the two peroxo oxygen atoms ($O-B-O$ within the ring). Therefore,there are $3$ different types of $O-B-O$ angles.
