In which of the following molecule, bonding is taking place in excited state?

In ${\mathrm{PCl}}_3$ , bonding takes place in ground state.
For the sake of simplicity, we will simply display the outer electrons in the case of ${\mathrm{PCl}}_3$. In ${\mathrm{PCl}}_3$, there are 2,8 electrons in the inner layers of each atom's orbit. There is a noble gas structure in every atom. Therefore, bonding in ${\mathrm{PCl}}_3$ does not occur in an excited state.
