Which of the following have the same number of unpaired electrons in $d$ orbitals?

Which one is wrong in the following statements?

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:

The transition metals have a less tendency to form ions due to

Given below are two statements:
Statement $I$: Iron$(III)$ catalyst,acidified $K_{2}Cr_{2}O_{7}$ and neutral $KMnO_{4}$ have the ability to oxidise $I^{-}$ to $I_{2}$ independently.
Statement $II$: Manganate ion is paramagnetic in nature and involves $p\pi-p\pi$ bonding.
In the light of the above statements,choose the correct answer from the options.

Given below are two statements:
Statement $I$: The number of pairs,from the following,in which both the ions are coloured in aqueous solution is $3$: $[Sc^{3+}, Ti^{3+}], [Mn^{2+}, Cr^{2+}], [Cu^{2+}, Zn^{2+}]$ and $[Ni^{2+}, Ti^{4+}]$.
Statement $II$: $Th^{4+}$ is the strongest reducing agent among $Th^{4+}, Ce^{4+}, Gd^{3+}$ and $Eu^{2+}$.
In the light of the above statements,choose the correct answer from the options given below:
