In which molecules resonance phenomenon operates-

Which molecule does not show resonance

Resonance phenomenon is generally involved when single valence bond structure could not represent the actual structure of the molecules or species. Based on the actual bond lengths, bond energies etc, of the molecules or species, resonance phenomenon will help to achieve at the correct structure of the species or molecules. Which of the following is the correct resonance structure of
