The horizontal line.
A horizontal line has a slope of 0. This would be expected on a graph where time is the x axis and distance is the y axis. Time would elapse but the distance would not change.
The correct option is 1.
We need to find a graph that indicates an object whose velocity is zero.
Velocity is the change in displacement with respect to time.
Let d represents displacement and t represent time.
Velocity is 0.
It means the slope of line must be 0.
A horizontal line has slope 0.
In option 1, the graph represents a line whose slope is 0. It means displacement is 0 for any interval of time. So, velocity is 0.
Therefore the correct option is 1.
i used to know but i learned it a long time ago sorry
