#### Figure shows the acceleration-time graphs of a particle. Which of the following represents the corresponding velocity-time graphs?

Since acceleration is constant, therefore there is uniform increase in velocity. So, the graph is a straight line slopping upward to the right. When acceleration becomes zero, velocity is constant. So graph is a straight line parallel to the time-axis.
