Answer

Brief Explanations:

Acceleration is the rate of change of velocity. When an object slows down, its velocity is decreasing. In the context of positive - direction motion, a decrease in velocity means the acceleration is negative. Stationary means not moving. Positive velocity just indicates motion in a positive direction but not slowing down. Positive acceleration means speeding up. Constant velocity means no change in speed or direction.

Answer:

D. negative acceleration
