Which resonance structure contributes more to the resonance hybrid of 7-(cyclohexa-2,5-dien-1-ylidene)cyclohepta-1,3,5-triene, A or B?

Because the negative charge in B is more delocalized, it is less stable and contributes more to the resonance hybrid structure than A.

Because the negative charge in B is less delocalized, it is more stable and contributes more to the resonance hybrid structure than A.

Because the negative charge in A is more delocalized, it is more stable and contributes more to the resonance hybrid structure than B.

Because the negative charge in A is less delocalized, it is less stable and contributes more to the resonance hybrid structure than B.
