Answer:
The correct option is 1.
Step-by-step explanation:
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.
[tex]v=\frac{\text{Change in displacement}}{\text{change in time}}[/tex]
Velocity is 0.
[tex]0=\frac{\text{Change in displacement}}{\text{change in time}}[/tex]
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.
