$\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
