Problem

The amount of strong acid in the flask shown here is to be titrated by a strong base.

A flask with strong acid is shown. Seven white spheres are shown in the solution depicting seven H plus ions. To the right of the flask is a burette with eight molecules of OH minus (depicted as a red sphere bonded to a white sphere) evenly spaced going up the burette. The letters A through D are used to label various positions going up the burette. Going from the bottom of the burette; letter A marks the second OH minus molecule; letter B marks the third OH minus molecule; letter C marks the fifth OH minus molecule; and letter D marks the seventh OH minus molecule.

Which mark on the burette next to the flask indicates the amount of base required to reach the equivalence point?
