The end point of an acid-base titration corresponds to the point where a pH indicator changes color. This indicates that the solution has reached a certain pH, which usually corresponds to the stoichiometric point of the reaction. The other options may occur before or after the true end point, and therefore may not accurately indicate the completion of the reaction.
