hard to argue with any of those
Frankly I don't know how to answer this question. I don't know if it is a trick question or not. Here is my problem. The equivalence point is the theoretical point at which the acid just neutralizes the base. The end point (different from the equivalence point) is the point in the titration where the indicator turns. We try very hard to make the equivalence point the same as the end point but usually they are not EXACTLY the same but close enough so that the titration error caused by that difference is quite small.
If this is a beginning chemistry class I would answer d. If this is an advanced class I would answer b. I hope this doesn't confuse you but I'll be glad to answer follow up questions on this.
