(B) The highest oxidation state observed in the first row transition metals is $+7$.In the first row, $Mn$ (Manganese) with the outer electronic configuration $3d^5, 4s^2$ shows a $+7$ oxidation state.It has a total of $7$ electrons in its outermost orbitals ($5$ in $3d$ and $2$ in $4s$), which can be involved in bonding, thus allowing it to exhibit a $+7$ oxidation state.
