The question in the image asks to choose the incorrect statement about velocity and acceleration vectors. Let's break down the options:

• a. The tangential acceleration vector is characteristic of the change in the magnitude of the velocity vector.
• b. All the above statements are incorrect.
• c. The normal (or perpendicular) acceleration vector points toward the curvature of the path.
• d. The total acceleration vector characterizes the change in both direction and magnitude of the velocity vector.

Analysis:

1. Option a is correct: Tangential acceleration relates to the rate of change of the velocity's magnitude.
2. Option c is correct: Normal acceleration points toward the center of curvature (as in circular motion).
3. Option d is correct: The total acceleration involves both the tangential and normal components, thus describing changes in both magnitude and direction.

Thus, option b is incorrect because not all the statements are wrong—only the assertion in option b itself is.
