If you have taken a calculus class then you can easily see the answer by realizing that the velocity graph should be the derivative of the displacement graph.

But in either case, first look at the displacement graph, and think about it's slope. A straight line has a constant slope right?
A velocity graph that matches the displacement graph should basically be a "graph of the slope" of the displacement graph. Because "velocity" is the rate of change of the position.
 
From the graph, the answer should be 2. It can be understood as the Brownian motion.
 
Are you looking at the same problem Hahong?

He was asking about number 36, which is the velocity and displacement graphs.
The answer is (1) btw...
