(A) The acidic character of oxides of elements in a group decreases as we move down the group because the metallic character increases and the non-metallic character decreases. In Group $15$,the elements are $N, P, As, Sb, Bi$. $P_2O_3$ is a non-metal oxide and is acidic. $As_2O_3$ and $Sb_2O_3$ are amphoteric. $Bi_2O_3$ is basic. Therefore,$P_2O_3$ is the most acidic among the given options.
