The figure shows the displacement-time graph of a particle moving on the x-axis. Then,
                   
| 1. | the particle is continuously going in a positive x-direction. | 
| 2. | the particle is at rest. | 
| 3. | the velocity increases up to a time \(t_0\), and then becomes constant. | 
| 4. | the particle moves at a constant velocity up to a time \(t_0\), and then stops. | 
 
| 1. | \(1~\text{ms}^{-1}\) | 2. | \(2~\text{ms}^{-1}\) m/s | 
| 3. | less than \(1~\text{ms}^{-1}\) | 4. | greater than \(2~\text{ms}^{-1}\) | 
Acceleration-time graph of a body is shown.
 
The corresponding velocity-time graph of the same body is: 
| 1. | 2. | ||
| 3. |  | 4. |  | 
The graph of displacement time is given below.
  
Its corresponding velocity-time graph will be:
| 1. | 2. | ||
| 3. | 4. |
