(C) In resonance structures,the nitrogen atom $(N)$ in the nitro group has a valency of $4$ (forming $4$ bonds). If $N$ forms $5$ bonds,it would exceed its octet,which is not possible for second-period elements like nitrogen. Structure $(C)$ shows the nitrogen atom forming $5$ bonds (one double bond with the ring,two double bonds with oxygens,and one single bond with the other oxygen),which violates the octet rule. Therefore,it is the most unlikely representation.
