The correct order of ONO bond angle in the given species is:
\( \mathrm{NO_2^{+}} < \mathrm{NO_2} < \mathrm{NO_3^{-}} < \mathrm{NO_2^{-}} \)
\( \mathrm{NO_2^{-}} < \mathrm{NO_3^{-}} < \mathrm{NO_2} < \mathrm{NO_2^{+}} \)
\( \mathrm{NO_3^{-}} < \mathrm{NO_2^{-}} < \mathrm{NO_2} < \mathrm{NO_2^{+}} \)
\( \mathrm{NO_2^{-}} < \mathrm{NO_3^{-}} < \mathrm{NO_2^{+}} < \mathrm{NO_2} \)
