Final answer:
The point that cannot lie between the other two is point B.
Step-by-step explanation:
The correct answer is point B. If points A, B, and C are collinear and AC>AB, then point B cannot lie between points A and C. This is because point B is closer to point A on the line than point C. If point B were to be between points A and C, then AC would have to be equal to or greater than AB, which contradicts the given condition AC>AB.
