(D) In the nitrate ion $(NO_3^-)$,the central nitrogen atom is bonded to three oxygen atoms. Due to resonance,the double bond is delocalized over all three $N-O$ bonds. Each $N-O$ bond has a bond order of $1 + \frac{1}{3} = 1.33$. The total negative charge of $-1$ is distributed equally among the three oxygen atoms,so each oxygen atom carries a partial charge of $-\frac{1}{3}$. Thus,the resonance hybrid shows three equivalent $N-O$ bonds with partial double bond character and each oxygen atom having a partial charge of $-\frac{1}{3}$.

The resonance hybrid of the nitrate ion $(NO_3^-)$ is represented by:
