Acceleration is zero,velocity is constant.

(A) The slope of a position-time graph represents the velocity of the object. Since the graph is a straight line,its slope is constant,which means the velocity of the object is constant. Acceleration is defined as the rate of change of velocity. Since the velocity is constant,the rate of change of velocity is zero. Therefore,the acceleration of the object is $0 \ m/s^2$ and the velocity is constant.
