The table gives the outcomes of heating four metals separately with oxides of different metals. The four metals are iron, copper, magnesium and Y. The results are displayed below. What is the order of reactivity of the metals, least reactive first?
- Acopper, iron, Y, magnesium
- Bcopper, Y, iron, magnesium
- Cmagnesium, iron, Y, copper
- Dmagnesium, Y, iron, copper
