Exhibiting maximum covalency in compounds

(C) $Be$ (Beryllium) and $Al$ (Aluminium) show a diagonal relationship. Both form amphoteric oxides,polymeric hydrides,and covalent halides. However,they differ in their maximum covalency. The maximum covalency of $Be$ is $4$ (due to the presence of only $2s$ and $2p$ orbitals),whereas the maximum covalency of $Al$ is $6$ (due to the availability of $3d$ orbitals).
