Decreasing order of stability :
  • A
    $\text{O}_2 > \text{O}^+_2 > \text{O}^{2-}_2 > \text{O}^-_2$
  • B
    $\text{O}_2^- > \text{O}^{2-}_2 > \text{O}_3^+ > \text{O}_2$
  • ✓
    $\text{O}_2^+ > \text{O}_2>\text{O}^-_2 > \text{O}^{2-}_2$
  • D
    $\text{O}_2^{2-} > \text{O}^-_2 > \text{O}_2 > \text{O}_2^+$
✓

Answer

Correct option: C.
$\text{O}_2^+ > \text{O}_2>\text{O}^-_2 > \text{O}^{2-}_2$
Greater the bond order, more will be stability.
