Solution

The correct option is B Its acceleration changes
When the paper just leaves the hand, the paper is in free fall. During free fall, any object has constant acceleration which is equal to $g = 9.8 m / s^{2}$ . The acceleration also changes the velocity of the paper. Thus, option B will correct.
