Final Answer :
D
Explanation :
The equilibrium expression for a reaction is written as the product of the concentrations of the products divided by the product of the concentrations of the reactants, each raised to the power of their stoichiometric coefficients in the balanced equation. In this case, the products are H+ and A-, and the reactant is HA, with all stoichiometric coefficients being 1.
