The correct answer is: 0,0
Formal charge $(\mathrm{FC})=\left[V-l p-\frac{1}{2} b p\right]$
[where, $V=$ valence electrons, $l p=$ lone pair and $b p=$ bond pair]
For
< smiles>O=C=[18O] < /smiles>
$\mathrm{FC}$ of $\mathrm{O}=6-4-\frac{1}{2} \times 4=0$
$\mathrm{FC}$ of $\mathrm{C}=4-0-\frac{1}{2} \times 8=0$
