The balanced reaction is:-

expression is:-

Explanation:

Benzoate ion is the conjugate base of the benzoic acid. It is a Bronsted-Lowry base and the dissociation of benzoate ion can be shown as:-

The expression for dissociation constant of benzoate ion is:

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
