The following can be deduced from the given v – t graph:

Concept: A velocity-time graph depicts the speed and direction of an object over a given time period. Speed-time graphs are another name for velocity-time graphs. The velocity of the object is represented by the vertical axis of a velocity-time graph. The horizontal axis represents the time since the beginning.

 In the above graph, the velocity is constant and it does not change with time. Therefore, the object is in uniform motion. There’s no acceleration acting on the object.

Hence, option 1 is the correct answer.
