Statement I: Down the group higher oxidation states become more stable in p-block
Statement II: Down the group lower oxidations states become more stable in d- block

I…Down the group higher oxidation states become stable in d-block;

Evidence- ${\mathrm{Cr}}_2{\mathrm{O}}_7^{-2}\left(+6\right)$ is a good oxidant but ${\mathrm{MoO}}_3\left(+6\right) \mathrm{and} {\mathrm{WO}}_3\left(+6\right)$are stable;

II….Down the group lower oxidation states become more stable in p-block;

Evidence-inert pair effect;
