$p-$block elements form only acidic oxides.

(B) $p-$block elements form acidic,basic,and amphoteric oxides. Therefore,the statement that they form only acidic oxides is incorrect. Additionally,for $p-$block elements,the oxidation states differ by $2$ units due to the inert pair effect (e.g.,$Pb^{+2}$ and $Pb^{+4}$).
