The correct statement regarding the given Ellingham diagram is:

Options

AAt ${1400}^{o}C, Al$ can be used for the extraction of $Zn$ from $ZnO$ .
BAt ${500}^{o}C,$ coke can be used for the extraction of $Zn$ from $ZnO$
CAt ${800}^{o}C, Cu$ can be used for the extraction of $Zn$ from $ZnO$
DCoke cannot be used for the extraction of $Cu$ from $C{u}_{2}O$

Correct answer

A. At ${1400}^{o}C, Al$ can be used for the extraction of $Zn$ from $ZnO$ .

Step-by-step solution

According to the Ellingham diagram, the species that is going to act as reducing agent should lie below the substance to be reduced at the particular temperature.

As is visible from the graph, at 1400^o C, the line of Al lies below the line of ZnO. Hence, Al can be used for reducing ZnO to Zn.
