Which of the following complexes exhibits the highest paramagnetic behaviour? (where $gly = \text{glycine}$,$en = \text{ethylenediamine}$,and $bpy = \text{bipyridyl}$ moieties. At. nos. $Ti = 22, V = 23, Fe = 26, Co = 27$)

Which of the following compounds cannot show coordination isomerism?

Match the List-$I$ with List-$II$:

List-$I$ (Complex ion)	List-$II$ (Calculated spin only magnetic moment $(BM)$)
$A$. $[Cr(H_2O)_6]^{2+}$	$I$. $3.87$
$B$. $[Co(H_2O)_6]^{2+}$	$II$. $5.92$
