Which of the following has largest bond angle?

The repulsion between bond pairs grows as the number of lone pairs of electrons increases, and they tend to become closer.

The electronegativity of the core atom rises as a result of this repulsion, and the bond angle decreases.

The order of  bond angles is, ${\mathrm{NO}}_2^{-}<{\mathrm{NO}}_3^{-}<{\mathrm{NO}}_2<{\mathrm{NO}}_2^{+}$
