A. a runner slowing down at the end of a race

Explanation: negative acceleration (deceleration) means the acceleration is opposite the velocity, causing the speed to decrease. The runner slowing down fits that; C is positive acceleration, D is zero acceleration, and B is acceleration due to gravity (usually taken as downward).
