Which of the following statements is incorrect?

• A
  The bond angle follows the order $109^{\circ}28' > 107^{\circ} > 104.5^{\circ} > 92^{\circ}$ (i.e.,$CH_{4} > NH_{3} > H_{2}O > H_{2}S$)
• B
  The bond order follows the order $O_{2}^{+} > O_{2} > O_{2}^{-} > O_{2}^{2-}$
• C
  Strength of $H$-bond follows the order $HF > H_{2}O > NH_{3} > HCl$
• D
  Of $\overline{O}-C \equiv \stackrel{+}{O}$ and $O=C=O$,the structure $\overline{O}-C \equiv \stackrel{+}{O}$ is the most stable structure
