The interpretation of a position-time graph is required.

The correct option is The velocity is zero.

In a position time graph the y axis denotes the position and x axis denotes the time.

A horizontal line where [tex]y\neq 0[/tex].

This means that the points of the line will be for some value of x, the y value will always be constant.

The slope of a position-time graph will gives the velocity of the object.

Slope is given by

[tex]m=\dfrac{\Delta y}{\Delta x}[/tex]

Here, since the graph is a horizontal line, [tex]\Delta y=0[/tex]

[tex]\Rightarrow m=\dfrac{0}{\Delta x}=0[/tex]

The velocity of the person will be zero.
