(B) The formation of a $p \pi-d \pi$ bond requires one atom to have a lone pair of electrons in a $p$-orbital and the other atom to have a vacant $d$-orbital.Oxygen has a lone pair in its $p$-orbital. For $p \pi-d \pi$ bonding,the other element must possess vacant $d$-orbitals in its valence shell.Carbon $(2s^2 2p^2)$,Nitrogen $(2s^2 2p^3)$,and Boron $(2s^2 2p^1)$ belong to the second period and lack $d$-orbitals in their valence shell.Phosphorus $(3s^2 3p^3 3d^0)$ belongs to the third period and possesses vacant $3d$-orbitals,allowing it to participate in $p \pi-d \pi$ bonding with oxygen (e.g.,in $PO_4^{3-}$ or $P=O$ bonds).

Which of the following elements can be involved in $p \pi-d \pi$ bonding with oxygen?
