Which one is wrong in the following statements?

Identify the correct option:
$(I)\ AgCl$ is not soluble in $H_2O$ but soluble in $KCN$.
$(II)\ Zn$ when reacts with cold v.v. dil $HNO_3$ gives $NH_4NO_3$.
$(III)\ CuSO_4$ reacts with $KI$ to form $Cu_2I_2 + K_2SO_4$.
$(IV)\ CuSO_4 \cdot 5H_2O \xrightarrow{1000\,^oC}$ The gases liberated are $SO_2$ and $O_2$.

Match the following:

List-$I$	List-$II$
$A$. Oxidation state of $V$ in $VOCl_2$	$I$. $0$
$B$. Number of unpaired electrons in $MnO_4^{2-}$ ion	$II$. $1$
$C$. Number of unpaired electrons in $[NiCl_4]^{2-}$ ion	$III$. $5$
$D$. This oxidation state is exhibited by all lanthanide ions	$IV$. $3$
	$V$. $4$
	$VI$. $2$

The correct answer is:

Given below are two statements:
Statement $I$: The number of pairs among $[Ti^{4+}, V^{2+}], [V^{2+}, Mn^{2+}], [Mn^{2+}, Fe^{3+}]$ and $[V^{2+}, Cr^{2+}]$ in which both ions are coloured is $3$.
Statement $II$: The number of pairs among $[La^{3+}, Yb^{2+}], [Lu^{3+}, Ce^{4+}]$ and $[Ac^{3+}, Lr^{3+}]$ ions in which both are diamagnetic is $3$.
In the light of the above statements, choose the correct option from the options given below:

Which of the following orders is correct?

Match the element in column $I$ with that in column $II$.

Column - $I$	Column - $II$
$(a)$ Copper	$(i)$ Non-metal
$(b)$ Fluorine	$(ii)$ Transition Metal
$(c)$ Silicon	$(iii)$ Lanthanoid
$(d)$ Cerium	$(iv)$ Metalloid
