Which of the following represents the correct order?

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

Consider the following elements $In$,$Tl$,$Al$,$Pb$,$Sn$ and $Ge$. The most stable oxidation states of elements with highest and lowest first ionisation enthalpies,respectively,are

Which of the following statements is not correct?

State whether the following statements are true or false:
$(i)$ As the atomic number increases in a period,the nuclear charge increases,therefore the ionization enthalpy increases.
$(ii)$ As the metallic character of elements increases,the atomic radius generally increases.
$(iii)$ $Mn$ $(Z = 25)$ is a transition element. Although it is a $3d$-orbital element,its position in the periodic table is in the $4^{th}$ period.

Match the following columns:

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	$S$. $N < C < O$
