Which of the following correctly describes the nature of the oxides $N X_{2} O X_{3}$ , $As X_{2} O X_{3}$ and $Bi X_{2} O X_{3}$ respectively?

Within group 15 the oxides become more basic down the group because the metallic character increases.

N X_{2} O X_{3}

(and

P X_{2} O X_{3}

) are acidic,

As X_{2} O X_{3}

and

Sb X_{2} O X_{3}

are amphoteric, and

Bi X_{2} O X_{3}

is basic.
