The correct answer is:
4
Configuration of $\mathrm{O}_{2}^{2-}=\sigma 1 s^{2}, \sigma^{n} 1 s^{2}, \sigma 2 s^{2}, \sigma^{n} 2 s^{2}$, $\sigma 2 p_{x}^{2}, \pi 2 p_{x}^{2} \approx \pi 2 p_{y}^{2}, \pi^{4} 2 p_{x}^{2} \approx \pi \pi_{p}^{2}$.
$\therefore$ Number of antibonding electron pairs is four.
$\therefore$ Number of antibonding electron pairs is four.
