Solution

The correct option is A $C O, N O^{+}, C N^{-}, C_{2}^{2 -}$
In option $A$ , each species contains 14 electrons
$C O =$ 6(carbon) + 8(oxygen) $= 14$
$N O^{+} =$ 7(nitrogen) + 8(oxygen) - 1(the positive charge) $= 14$
$C N^{-} =$ 6(carbon) + 7(nitrogen) + 1(the negative charge) $= 14$
$C_{2}^{- 2} =$ 6(carbon) + 6(carbon) + 2(-2 negative charge) $= 14$
So, $A$ is the correct answer.
