Solution

The correct option is A Y will reduce oxide of Z.
An Ellingham diagram is a graph showing the temperature dependence of the stability for the compounds. This analysis is usually used to evaluate the ease of reduction of metal oxides and sulphides.

Features-
1. The lower the position of a metal's line in the Ellingham diagram the greater the stability of its oxide.
2. Stability of Metallic oxide decreases with increases in temperature.
3. For a given temperature if 2 metals are compared, the metal with lower Gibbs free energy of oxidation on the diagram will reduce the oxide with higher Gibbs free energies.
4. The greater the gap between any two lines the greater the effectiveness of reducing agents to the lower line.
5. The intersection of two lines implies an oxidation-reduction equilibrium.

So, by this point no. 3: Y will reduce oxide of Z.
