Answer :
The greatest contributor to the resonance hybrid is the resonance form with the smallest formal charges. The main resonance contributor is the one with the lowest energy. The question was incomplete, this is a general answer.
Resonance contributors
We can write some Lewis structure for a molecule, differing only in the positions of the electrons. The most stable structure contributes the most to the resonance hybrid. Any of a set of Lewis structures that differ only in the distribution of electrons in covalent bonds and single pairs. the weighted average of the resonance contributors gives the hybrid resonance. It often occurs in structures when the double bond lies opposite the single bond and forms two identical Lewis structures. The point of this is that double bonds and single bonds from one molecular structure can move or exchange positions so as to form a structure that is identical to the previous molecular structure. For example on O₃ (ozone).
