11the second one.. can be done by the ellingham diagram concept...
The Ellingham curve for Aluminum always lies below the curves of metals like Cr, Fe, Mn and Ti. So Aluminum can be used as the reducing agent for oxides of all these metals.
thus my answer is Ba.
as MgO can be reduced by iron at very high temperature approximately about 1100°c..
