(B) $NH_3$ acts as a weak field ligand with $Ni^{2+}$.The electronic configuration of $Ni$ $(Z=28)$ is $[Ar] 3d^8 4s^2$.For $Ni^{2+}$,the configuration is $3d^8$.The $3d$ orbitals are filled as follows: two orbitals are doubly occupied,and two orbitals are singly occupied (total $2$ unpaired electrons).The spin-only magnetic moment is calculated as:$\mu = \sqrt{n(n+2)} \ BM$Where $n = 2$ (number of unpaired electrons).$\mu = \sqrt{2(2+2)} = \sqrt{8} \approx 2.82 \ BM$.To express this as $x 	imes 10^{-1} \ BM$,we have $2.82 = 28.2 	imes 10^{-1}$.Rounding to the nearest integer,$x = 28$.

List-$I$ (Complex)	List-$II$ (Type of isomerism)
$A$. $[Co(NH_3)_5(NO_2)]Cl_2$	$I$. Solvate isomerism
$B$. $[Co(NH_3)_5(SO_4)]Br$	$II$. Linkage isomerism
$C$. $[Co(NH_3)_6][Cr(CN)_6]$	$III$. Ionization isomerism
$D$. $[Co(H_2O)_6]Cl_3$	$IV$. Coordination isomerism

The 'Spin only' magnetic moment for $[Ni(NH_3)_6]^{2+}$ is $ . . . . . . \times 10^{-1} \ BM$.
