graph 2 corresponds to the highest velocity
graph 1 corresponds to zero velocity
graph 3 corresponds to a particle moving in the negative x direction
graph 2 corresponds to a particle moving in the positive x direction

But according to the correct option, it stated zero velocity.
I don't think that is right.
They should have written constant velocity and not zero velocity.
It is constant velocity, zero acceleration.
if you take a good look at the graph 1, you would see that there is a constant displacement irrespective of the value of the time meaning change in displacement is zero and v= ∆d/∆t. if ∆d is zero then v is zero. since acceleration due to gravity =∆v/t then g=0/t . Therefore g=0. Option B
Graph 1 corresponds to zero velocity because it's at constant speed where change in the two velocity is zero i.e V-V/t = 0/t =0
