An x vs.t graph is drawn for a ball moving in one direction.The graph starts at the origin and at t = 5 s the velocity of the ball is zero.We can be positive that at t = 5 s,
A)the slope of the curve is non-zero.
B)the ball has stopped.
C)the acceleration is constant.
D)the curve is at x = 0,t = 0.

At t=5s, the velocity of the ball is zero which means the ball has stopped. This is indicated by the intersection of the x-axis and the graph. The slope of the curve is zero at this point. The acceleration may or may not be constant, and the curve could be at any value of x as it depends on the initial conditions of the motion.
