The figure given below shows the displacement and time, \((x\text -t)\) graph of a particle moving along a straight line:

The correct statement, about the motion of the particle, is:

1. | the particle moves at a constant velocity up to a time \(t_0\) and then stops. |

2. | the particle is accelerated throughout its motion. |

3. | the particle is accelerated continuously for time \(t_0\) then moves with constant velocity. |

4. | the particle is at rest. |
