The equivalence point of an acid-base titration is the point where the acid and base have been added in proper stoichiometric amounts. At this point, all of the acid has been neutralized by the base or vice versa, resulting in a neutral solution. The other choices are not necessarily true of the equivalence point - the use of equal volumes of reactants can occur at other points during the titration, and the pH indicator changing color is simply an indicator of the pH changing, not necessarily the equivalence point specifically.
