The correct option is B

A) Both of them are d-orbitals and they overlap laterally to form $d\pi -d\pi$ bond.

B) The lateral overlap of s-orbital is not possible and will not give rise to bonding.

C) p-orbital and d-orbital overlap laterally to form $p\pi -d\pi$ bond.

D) Both of them are d-orbitals and they overlap laterally to form $d\delta -d\delta$ bond.
