Based on the compounds of group 15 elements, the correct statement(s) is (are)

$\left(A\right)$ $B{i}_2{O}_5$ is metallic oxide but $N_2{O}_5$ is non metallic oxide therefore $B{i}_2{O}_5$ is basic but $N_2{O}_5$ is acidic.
$\left(B\right)$ In $N{F}_3 , N \mathrm{a}\mathrm{n}\mathrm{d} F$ are non metals but $Bi{F}_3 , Bi$ is metal but $F$ is non metal therefore $N{F}_3$ is more covalent than $Bi{F}_3$
$\left(C\right)$ In $P{H}_3$ hydrogen bonding is absent but in $N{H}_3$ hydrogen bonding is present therefore $P{H}_3$ boils at lower temperature than $N{H}_3$
$\left(D\right)$ Due to small size in N-N single bond l.p. - l.p. repulsion is more than P-P single bond therefore N-N single bond is weaker than the P-P single bond
