detailed solution

Correct option is C

An element $X$ occurs in short period having configuration $n s^{2} n p^{1}$ . The formula and nature of its oxide is $X_{2} O_{3}$ , amphoteric.

The arrangement of the III A (B) group components is $n s^{2} {np}^{1}$ . They produce type $X_{2} O_{3}$ oxides, which should either be B or Al because it belongs to the short chain. B produces acidic oxides, whereas Al produces amphoteric oxides.

Hence, option C is correct.
