Which of the following points is never the same for $IP$ and $EA$?

Choose the correct option regarding the following statements:
Statement-$1$: Nitrogen has lesser electron gain enthalpy than oxygen.
Statement-$2$: Oxygen has lesser ionization enthalpy than nitrogen.

The isoelectronic set of ions is

Which of the following is incorrect for the indicated property?

Which one among the following statements is/are not correct?
$I$. $Ba$ compounds,generally are more covalent than $Be$ compounds.
$II$. The electron gain enthalpy of $He$ is positive.
$III$. The oxidation state of $O$ in $OF_2$ and $Na_2O$ are same.
$IV$. The radius of $Na^{+}$ ion is smaller than that of $F^{-}$ ion.

Consider the following statements:
$(i) Na_2O < MgO < ZnO < P_4O_6$ - Acidic property
$(ii) F > Cl > Br$ - Electron gain enthalpy
$(iii) M^{2-} > M^{-} > M^{+} > M^{2+}$ - Ionic size
$(iv)$ The second ionisation enthalpy of $Cu$ is more than the second ionisation enthalpy of $K$.

$(a)$ $T, T, F, F$
$(b)$ $F, T, F, T$
$(c)$ $F, F, F, T$
$(d)$ $T, F, T, F$
