What causes variation in velocity of a particle ?

Figure shows the position the graph for a particle in one dimensional motion. Which of the graphs in fugure represent the variation in the velocity of the particle with time ?

Figure given here shows the variation of velocity of a particle with time. Find the displacement. ,
