(B) $Zn$ and $Hg$ have completely filled $d$-orbitals in their ground state electronic configurations:$Zn (Z=30): [Ar] 3d^{10} 4s^2$$Hg (Z=80): [Xe] 4f^{14} 5d^{10} 6s^2$Elements exhibit variable valency primarily due to the participation of electrons from incompletely filled $d$-orbitals in bonding. Since $Zn$ and $Hg$ have stable,fully filled $d^{10}$ configurations,they do not exhibit variable valency.

$Zn$ and $Hg$ do not show variable valency like other $d$-block elements because ...
