Solution

The correct option is A (I), (II) and (III)
All statements are correct.

$B_{2} O_{3} \to a c i d i c$

$A l_{2} O_{3}$ and $G a_{2} O_{3}$ are amphoteric oxides.

$I n$ and $T l$ oxides are basic in nature.

As we go down the group non-metallic character decreases and metallic character increases.
