Which of the following represents the correct order of ionization enthalpy?
$(i) Ba < Sr < Ca$
$(ii) S^{2-} < S < S^{2+}$
$(iii) C < O < N$
$(iv) Mg < Al < Si$

Match the following properties in Column-$I$ with their correct trends in Column-$II$:

Column-$I$	Column-$II$
$A$. Ionisation potential	$P$. $O < F < N$
$B$. Electronegativity	$Q$. $N < O < F$
$C$. $Z_{eff}$	$R$. $O < N < F$
$D$. Electron affinity	$S$. $N < C < O$

Match the column-$I$ with column-$II$

$A. S \rightarrow S^{-}$	$P. \text{Endothermic process}$
$B. N^{-} \rightarrow N$	$Q. \text{Exothermic process}$
$C. O^{-} \rightarrow O^{2-}$	$R. \text{Inert gas configuration in product}$
$D. P \rightarrow P^{-}$	$S. \text{Half filled configuration in product}$

Correct match is $:-$

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 $K$.
Which of the following is the correct representation of True $(T)$ / False $(F)$ for the given statements?

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