Which of the following statements is correct?

The atomic numbers of elements $A, B, C$ and $D$ are $Z-1, Z, Z+1$ and $Z+2$,respectively. If $B$ is a noble gas,choose the correct statements from the following:
$(1)$ $A$ has high electron affinity
$(2)$ $C$ exists in $+2$ oxidation state
$(3)$ $D$ is an alkaline earth metal

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

State whether the following statements are true or false:
$(i)$ Higher the ionization enthalpy,lower the screening effect.
$(ii)$ The ionization enthalpy of $Be$ is higher than that of $B$.
$(iii)$ The shielding effect increases as we move from left to right in a period.
$(iv)$ The increasing order of the first ionization energy is $B < Be < O < N$.

Given below are two statements:
Statement-$I$: $C < O < N < F$ is the correct order in terms of first ionization enthalpy values.
Statement-$II$: $S > Se > Te > Po > O$ is the correct order in terms of the magnitude of electron gain enthalpy values.
In the light of the above statements, choose the correct answer from the options given below:
