Solution

The correct option is B $N {O_{3}}^{-}, C {O_{3}}^{2 -}$
Answer:

Atoms and ions that have the same electron configuration are said to be isoelectronic.

Number of electrons in $N O_{3}^{-}$ = 7 (in nitrogen) + 8 (in oxygen) x 3 (three oxygen atom) + 1 (1 from negative charge) = $32$

Number of electrons in $C O_{3}^{2 -}$ = 6 (in carbon) + 8 (in oxygen) x 3 (three oxygen atom) + 2 (2 from negative charge) = $32$
Hence they are the pairs of isoelectronic.

Option B is correct
