Answer : The correct alphabetical order will be, CDE
Explanation :
Equilibrium constant : It is defined as the ratio of concentration of products to the concentration of reactants. It is represented as
.
The given balanced equilibrium reaction is,

As we know that the concentrations of pure solids are constant that means they do not change. Thus, they are not included in the equilibrium expression.
The expression for equilibrium constant for this reaction will be,

or,

From the expression of equilibrium constant we conclude that the alphabetical order will be, CDE.
Hence, the correct alphabetical order will be, CDE
