Statement – 1 : PbO₂ is an oxidising agent and reduced to PbO.

Pb (lV) in PbO₂ gains electrons to form Pb(ll) in PbO Hence it is an oxidizing agent
Statement – 2 : Stability of Pb (II) > Pb (IV) on account of the inert pair effect.

The inert pair effect is the tendency of the electrons in the outermost atomic s-orbital to remain un-ionized or unshared in compounds of post-transition metals. That is the reason PbO₂ acts as an oxidising agent and readily reduces to PbO.
