In structure C, oxygen - the atom more electronegative than carbon - has a positive charge. This would be a highly unstable form and hence does not contribute to the resonating structure.
Another way to look at it would be that -NO2, a -I and -R group appears to show +R effect in structure C, which is incorrect.

To determine the correct answer:
- Resonance structures are different ways of drawing the same molecule that differ only in the placement of electrons, not in the positions of atoms. The position of atoms and bonds must remain the same in resonance structures, but electrons (lone pairs or bonds) can be moved.
- In this case, for 1-nitrocyclohexene, resonance would involve delocalizing the electrons in the nitro group (-NO₂) onto the ring system.
Option A shows a valid resonance structure where the electrons of the nitro group are delocalized.
Option B also shows a valid resonance structure with delocalization of the electrons from the nitro group to the ring.
Option C shows a resonance structure, but it includes an incorrect placement of charges or does not fully satisfy the rules for resonance structures.
Option D shows a valid resonance structure as well.
Thus, Option C is the answer, as it is not a correct resonance structure of 1-nitrocyclohexene.
Answer: Option C
