Answer

Explanation:

Step1: Recall free - fall motion

When there is no air resistance, an object in free - fall near the surface of the Earth experiences a constant acceleration due to gravity, approximately $g = 9.8\ m/s^{2}$.

Step2: Analyze the acceleration - time graph

The acceleration of the book is constant throughout its fall. A constant value of a quantity over time is represented by a horizontal line on a graph of that quantity versus time.

Answer:

D. Graph A
