Consider the following conversions:
$(i) \, O_{(g)} + e^- \to O_{(g)}^{-}, \Delta H_1$
$(ii) \, F_{(g)} + e^- \to F_{(g)}^{-}, \Delta H_2$
$(iii) \, Cl_{(g)} + e^- \to Cl_{(g)}^{-}, \Delta H_3$
$(iv) \, O_{(g)}^{-} + e^- \to O_{(g)}^{2-}, \Delta H_4$
Based on the given information,which statement is incorrect?

• A
  $\Delta H_3$ is more negative than $\Delta H_1$ and $\Delta H_2$
• B
  $\Delta H_1$ is less negative than $\Delta H_2$
• C
  $\Delta H_1, \Delta H_2$ and $\Delta H_3$ are negative whereas $\Delta H_4$ is positive
• D
  $\Delta H_1$ and $\Delta H_3$ are negative whereas $\Delta H_2$ and $\Delta H_4$ are positive
