Solution

The correct option is A $N O_{3}^{-}, C O_{3}^{- 2}$
Number of electrons in the compound is :
$N O_{3}^{-} = 32 e^{-}$
$C O_{3}^{2 -} = 32 e^{-}$
$C l O_{3}^{-} = 42 e^{-}$
$S O_{3}^{-} = 41 e^{-}$
Therefore, $N O_{3}^{-}$ and $C O_{3}^{2 -}$ are isoelectronic
The structures of both $N O_{3}^{-}$ and $C O_{3}^{2 -}$
is trigonal planar.
Therefore $N O_{3}^{-}$ and $C O_{3}^{2 -}$ are isostructural also.
