B. `Al_(2)O_(3)`
C. `Ga_(2)O_(3)`

Answer 1

Correct Answer - A
The acidic nature of oxides changes from acidic to basic through amphoteric on moving down the group.
`underset(underset("less basic")("More acidic"))(underbrace(B_(2)O_(3))), underset("Amphoteric")(underbrace(Al_(2)O_(3) and Ga_(2)O_(3))), underset("Basic")(underbrace(ln_(2)O_(3) and Tl_(2)O_(3)))`
